I’m debating leaving my LTR to move overseas

r/

I’ll start out by saying I love my partner dearly, we’ve been together for over 6 years now. I turned 30 last year and just feel very stagnant and unhappy with parts of my life. I’m unhappy with my career and have been wanting to make a major change for years now. I don’t have any close friends that I see on a regular basis. The US political climate scares me and weighs on me daily. I’m a dual us/uk citizen and I’m wanting to move over there soon. The biggest hesitation I have is leaving my partner. He wants to stay here and I understand that. We’re poly and have our own lives. We don’t live together either. He’s my main emotional support person and idk what our relationship would look like if I left. I know we’ll visit each other but it’ll only be a couple times a year probably. I don’t want to not live my life because of fear of losing this man as I know I would resent myself for prioritizing him over my own wants. I just go back and forth and it would be such an amazing adventure and I may never get this opportunity again in my life where I have the means to move across the globe. How do I know what I should do? I’ve already set in motion my move but I’m so scared I’m making a huge mistake. I’m terrified of regret but I know that’s an awful reason not to chase something. Starting over would be an amazing opportunity to get to know myself. Everyone in my life supports my decision and is happy for me but I haven’t made any big changes in my life in so long. I’ve been in the same home for almost a decade now. I’ve always lived in the same area. I’ve been in the same circles a long time now too. Maybe it’s time to explore more of life. Ugh idk what to do.
