Should I leave my boyfriend?

Hello, I am making this post because I genuinely need some solid advice on whether or not I (20F) should leave my (24M) boyfriend.

There’s quite a few things he’s done that have made me think about walking away, we’ve been together for only 3 months and I’m worried for the path of our relationship at this state.

I can’t remember everything in chronological order so I will just try my best to recap everything in a clear way. The first time I ever got a odd feeling was in the very beginning when we first started dating and we were texting, talking about mental health and I mentioned that I had been inpatient at a hospital 3 times after my moms passing and he made the remark that I better not go back into the hospital because he might leave me. Which at that time I was trying to be understanding because maybe he just wouldn’t want to deal with that worry, totally understandable… however, everytime since then that I’ve mentioned needing mental health support he’s always been odd about it, by telling me I just need hobbies and friends and I don’t need the medicines they put me on. I did stop taking all of my meds once he started to say that stuff and I’ve also stopped therapy, the friends and hobbies thing isn’t going so well at the moment though.

Secondly, when we first started talking I mentioned I’m a bigger girl and struggle with being insecure about my weight, he said my weight is not a problem and he’s dated bigger, flash forward to after our first hang out and he started to tell me I need to go on a weight loss medicine and even asked his mom for suggestions on how to get it… I did eventually start taking an weight loss injection, but the way he was constantly mentioning it beforehand made me uncomfortable and I told him I understand he’s concerned for my health but it felt like a jab because while I knew my weight was a bit much I tried not to think too negative about it but with him around now all I do is take the shot and count calories like he’s told me too.

Thirdly, this one has caused quite a few arguments in our relationship and I will admit fault for this because I do have jealousy issues, but he talks about his ex girlfriend’s a lot, and even keeps in contact with some of them. He did block one when we first started talking to make me feel comfortable (which he ends up throwing that fact in my face later on). However, one day an ex of his popped up on my suggested friends list and I thought she was pretty so I did mention it to him and the conversation went like this

Me: “I think (exs name) is pretty
Him: “yeah all of my exes are beautiful, if you ever saw a picture of (other ex gf of his) youd be really insecure”

And that genuinely hurt my feelings to the core, because he did NOT have to say all of that?? I decided at that point that I didn’t like exes being a conversation so I told him “hey I don’t like that you talk about your exes that much because it tends to make me uncomfortable” and he tried to fight back saying he doesn’t talk about them much and I’m just taking stuff too personally, eventually he caved and said he’d stop. However, the next time we hung out the entire first half was him talking about one of his exes again and he even acknowledged he knew it made me uncomfortable but still kept talking. Then, a few weeks ago we hung out and he mentioned he was talking to his ex (the one I said was pretty) about me and she started making snarky remarks, he claims he only reached out to her to get some advice for me about how to take care of myself because in his eyes I lack hygiene. I asked him to please not mention me to another ex because the things she said about also hurt, and it just feels weird to go to your ex about your current girlfriend in my mind??

Going off the fact he thinks I lack hygiene skills, he also has gotten mad at me several times because of what I like to eat, I will admit that for 20 years old I have the same eating habits of a 5 year old, I tend to stick to pizza, chicken tenders, etc etc, this ticks him off because he likes all kinds of food and he has tried a few times to get me to eat something new, like sushi, unfortunately that didn’t end well no matter what roll I tried. That alone I can see is probably frustrating for him but it’s hurtful to me when he flips it back to me and says my taste in food is so bad because I grew up poor with a single mother who didn’t care about me enough to make me eat proper foods, which is insulting to me and also my mom.

I can’t think of anything else he’s done at the moment, there’s been a lot of one off small things. However, I’ve tried to see things from his point of view and try not to take his words so personally and try to better myself but honestly I just feel more lost. He is a very nice guy, my family does love him and I love him too but sometimes I wonder if the hurt feelings is worth it. I can’t help but feel like maybe I’m too sensitive and I’m asking for too much? He’s never once apologized for anything he’s said or done even if I tell him it hurt me, it’s always a case of “you’re twisting my words” “you know what I meant” “you don’t trust me because I can’t be honest with you then” and it hurts because all I want is a man that’s gentle with me, I know that the world isn’t sunshine and rainbows but I would like to at least have something sweet.

Edit: adding this onto the post because I just remembered it!! One time he told me I wasn’t as lucky as his exes due to the fact he blocked that one ex for me because according to him his other exes used to have the “privilege” of texting her when he was acting “off” and she could listen to them and was understanding…and I thought that was the biggest plate of BS because why would I need to run to your ex because of your behavior??

TL;DR: my boyfriend has done a lot of things that have upset me in the past 3 months with no real care and I’m not sure if I’m too sensitive or if I need to leave him.
