worried if i have to give up on my person

Could this be OCD or is this a valid reason to want to cut things off. I like a Muslim man, but I’m not. He lives in Europe and I live in the US, and I feel like this has created a huge rift for me. I’ve started to give up on the idea of pursuing this because I don’t want to get married early and I don’t want to waste his time on someone that doesn’t have his beliefs. What is the best course of action?

my thoughts are screaming at me telling me that i dont want my relationship anymore and that i realized i lost feelings. i have a beautiful relationship of two years with a beautiful boy that loves me dearly and i deal with this thoughs for a year and a half. Im so scared it feels so real im scared i have changed and my last therapy session made it worse she basically told me i have to realise the thoughts are true and stop lying to myself. And made me think i am so scared and heartbroken bc i put high expectations on myslef to be with my boyfriend for all my life. Maybe i dont want to hurt him??? im always questioning my feelings for him 24/7 for over a year. I wm tierd

For some time i was obsessing over relationship with my girlfriend. For a long time we we're each other's best friends and we only had each other. Recently she made a good friend in work and im obviously really happy for her because she deserves to be loved by more people than me. But i started to feel really jealous. I never thought she can cheat on me i just have really low self esteem and i started to obsess over if she is still in love with me or if she is still attracted to me bc she sometimes would be more interested to spend time with that friend and not me. We talked about it a lot and i tried my best to not be jealous and give her space but i felt how she's distancing from me. At some point she stopped showing me her love in any way. She stopped hugging me and kissing me and she kinda stop telling me she loves me. She only responded "me too" when i told her i love her. I talked about it with her few times and she always said she understands and that she's tired and don't really need physical touch etc. But i was still worrying bc i just knew something is off. She really was acting different. And then few days ago she told me she's actually tired not because of job but me. She feels irritated by me and she don't know why and that she actually thought about breaking up with me and she don't know what to do because she's confused about her own feelings. She said she thinks she still loves me but it's hard for her to see a difference between friendship and love and that she feels tired of concept of dating someone. She said we should wait and see bc she thinks she still loves me but i don't know if that's honest. I don't know what to do anymore im crying all the time every day since that conversation we had. I feel like my worst nightmare just came true and now it's real and not only a though in my head. I can't do anything and i feel like it's the end of the world. We're living together and i don't want to go back to my parents but that's not the worst thing. I just love her so much and i can't hande thought of loosing her. My ocd made me question every single thing about me but somehow i never questioned my love for her so that's why I'm so emotional about it. I don't want to lose her. I don't know what to do i just want to be loved but I don't want anyone else. I don't know what to do im so scared. I want to die every time i look at her with love in my heart and i know she doesn't think about me like that anymore.
