I (30F) am leaving my husband (33F) of 6 months

I (30F) AM divorcing my husband (33M) of 6 months because he decided to have an open marriage. We have been together for 9 years prior to the marriage, and this was never something he mentioned he wanted. Some background: In July of 2024 he asked me to get off of my bipolar medication that I’ve been taking since 2019 because he “preferred me to be my natural self”, so being an idiot, I did. About 3 weeks before the wedding, he requested I sign a prenuptial agreement, which I, unfortunately, did. We got married in October.

When November rolls around, he states that he thinks we should open the relationship.
For context, I am an avid reader, and I read a lot of smut, which includes reverse Harems and situations where there are open relationships. So I’m not opposed to polyamory and was willing to give it a shot even though I was definitely uncomfortable with the suggestion. I laid down ground rules that we could only date together and that we wouldn’t do one on one dates with people and only threesomes or swapping since that’s what I’m the most familiar with. It was a very firm rule for me that we’d never be intimate without each other present.

We did end up having a threesome with a straight male that he picked out in December, which I didn’t necessarily enjoy, and it felt off to me. He said he enjoyed it a lot. We continued to stay on dating apps and had a second threesome with another male that he picked out, which I did actually enjoy this time, but he was also straight. For some reason, he never suggested another female.

About a week after the second threesome he said he met a gay man who wanted nothing to do with me and just wanted to suck him off, and he wanted to go meet him alone. He never previously suggested that he was interested in men. I obviously said no since that broke my boundary I had laid out, and he pitched a fit. He kept on about it until his birthday when he basically said, “I don’t really care what you want. I’m renting a hotel room downtown and getting some from this guy.” He preceded to buy a $300 dollar hotel room and left for about 3 hours and came back telling me how great it was. Obviously, I didn’t approve and told him that. I said if he wanted to do things like this, then I wanted to close the relationship. He said no.

He continues to see this man occasionally, taking him out on dates and spending time with him. He wanted to take him on a trip for Valentines Day weekend. Which is our first valentines Day as a married couple, and I lost it on him and said if he did that, I would want a divorce, and he was extremely angry that I said that. Fortunately, this guy broke up with him because he didn’t like that the guy he was dating had a wife, so I thought it was over. Nope.

He joined grindr and exclusively started talking to gay me. I was obviously feeling left out and betrayed at this point. He broke the rules that we had originally agreed to. I went on a date and was assaulted. Came home bruised and in pain, and he just said, “I think you need to pick better guys. Let me pick them out for you.” I said that I wanted to close the relationship. That I didn’t want this and he said that he didn’t want to. He picked out a straight guy for me, and I did end up having sex with him twice because I was lonely. My husband was going on dates with at least 11 men that I know about and having sexual relations on each date.

One day, my husband told me he found a website that gives you free std testing and HIV medication, and he wanted us to join it. I did, and I was STD free, but it messed with me that he wanted to get on Prep cause he knew he’d continue sleeping with other men. I told him again that I wanted to close the relationship, and he said no.

I joined Bumble, and I met a man who knows I am married but is still interested anyway. I tell my husband that I’m going to meet him that weekend and I do. I had a great time, and he’s extremely respectful, and I was enjoying my time with him. My husband knew I was going for the night, but he messaged me at 7 pm saying that I needed to come home immediately or something bad was going to happen. So I did leave, even though I was an hour and a half away. I get home, and he ignores me. We go to sleep. The next morning, he tells me that he brought a man into our house and was unhappy with what happened while he was there, and that’s the reason he called me back. He told me he wasn’t gay anymore.” He also tells me he doesn’t want me to talk to the man I was with anymore because he didn’t pick him out. I ignored that and continued speaking with him.

A week later we were supposed to go out of town together, but he tells me some other dude he met wanted to meet up and he was going to drop me off at my friend’s house and go stay at a hotel with him instead. He did drop me off, and I had the guy he didn’t want me to see again come and take me on a date. Again, I had a great time. This is when I decided to divorce my husband.

I tell him that I need space and that I’m strongly considering leaving him and I was going to stay with my friend until I made an official decision. He said, “Do what you need to do, but i want to be with you. I meant what I said when we exchanged vows.” I call bullshit on that. I move in with my friend and continue to go on dates with the other guy (no sex). I realize that I definitely don’t need to return to the relationship I was in and meet with my husband to tell him I want a divorce for sure. He begs me to stay, and my dumb ass goes back. He continues to treat me like shit and point out all my flaws without acknowledging his, like he has done for 9 years. I move out again 3 days later without saying a word in person. Sent him a text saying I was done and couldn’t see or speak to him anymore and blocked him.

He sent an email saying that I agreed to an open marriage, and it was my fault for agreeing. That I never should have said okay and that if he’d known this was going to happen, he wouldn’t have suggested it. He sent me divorce papers but said, “This is a draft, but I really wish you would reconsider and speak to me face to face. I want you to be my wife, and I love you. ”

I’m now planning on signing those papers and sending them via mail because I never want to speak to him or see him again. I can’t get any money because I signed a prenuptial agreement, but I just want out at this point. I also got back on my bipolar medication 2 weeks ago and feel much better.

What would you do in my situation, and do you think I made the correct decision?
