Really struggle to understand why this happened to me in the middle of such a good relationship.

So I have never got to tell my story out of all the forums that I’ve read and I just wanna share mine. Any advice is appreciated or similar stories are welcome to be shared. I met my boyfriend about a year and a half ago I just really knew of him but one night at a party I approached him and we talked and from then he played kinda hard to get so I just kept asking him to go on a date.. and that was all it took. We were connected like whole heartedly. I always said that I had found my lobster. I have always struggled with having extreme jealousy issues. Always assume the others cheating or that they don’t love me or like scared they will go out and be with other girls. 6 blissful months went by and then one morning I woke up and just felt like a switch had flipped. I was devastated this was what I believe is the love of my life and now I woke up just confused. Questioning my love, if it was true, someone else. It was horrible. And still is.

Hey I’m in a relationship that is so good and strong but I keep having thoughts even when we are together “oh you don’t love him” or “this isn’t really what you want “ “ you feel so much better alone etc” can anyone relate?

I think that’s what it is .. I’ve been through a lot with relationships .. I’ve never had good luck with them .. after taking two years off of dating and not wanting to date except hook up or have fun i meet a woman who wanted the same ..well we happened to like eachother alot and get into a relationship.. she ends up being amazing and super supportive of my and mental issues. One moment I’m secure and confident and then the next after three months together start my normal ocd process of questioning if I wanna be here if she’s the one if I love her or if there’s someone else .. it’s really annoying even though I know I really don’t wanna leave but I still obsess about it.. we’ll now I’m in the headspace of doubting she loves me or maybe she’s tired of me already even though nothing different has changed .. I don’t want reassurance and to nag about if she loves me .. when I thought about this stuff a couple weeks ago I asked and she told me flat out she loves and cares about me and thinks I’m amazing .. that thought of wondering if she loves me then turned around again to me thinking what if I don’t love her or wanna be here ? Lmfao is that relationship ocd or am I just really damaged .
