someone please help

i couldn't take this anymore. maybe i'll just let ocd win this time. it's too hard to not have a clear conscience everytime i'm with my bf cuz my mind is telling me i'm unfaithful and don't deserve to be happy. i feel like i'll never get better anymore. i already told myself many times to stop attracting attention from other people especially to people i'm having false attraction to. but i did it again yesterday, right after i smiled a little extra in front of that girl i might be attracted to i could feel the massive anxiety in my chest. already decided last week that i might be actually attracted to her so it's best to fully avoid her. i avoided her with the best i could, but we're in the same classroom and i saw her in my peripheral vision looking at us (my bf and i) whispered to myself not to make any mistake i'll regret, but then i felt like i lose control and laugh a little extra. i searched micro cheating and it says there "trying to impress someone you're attracted to" and now i want to break up with my bf. the guilt is too strong. i couldn't sleep at night.

I feel awful that I keep coming on here whenever I’m down bad but oh my gosh OCD is the most painful shit that I have EVER experienced in my life and I have a physical chronic illness…. I hate to say it but I hate living right now it’s too painful… im crying as I type to the point where my stomach is hurting, I have pretty severe ocd I do have generalized anxiety and idk if that is connected with ocd but because of that I have most of the subtypes REAL EVENT OCD,POCD,ZOCD,ROCD,SOCD HARM OCD, you name it and I got it!!! a lot of also why I have have those theme is trauma growing up and involving those things^ as of right now i’m 25 and a women with the most loving boyfriend in the entire world before my ocd hit me I NEVER questioned my love and care and attraction with the love of my life I always knew I was going to marry and be with this person the rest of my life! Now with ocd it confuses me soooo much and now I think I’m gay and didn’t realize or indenial and listen I get it “don’t look for reassurance!” “It’s not the thing ocd is attacking that is the problem ocd is the actual problem!” Here’s the thing with that if I’m in a relationship and I’m gay that would mean I would have to leave that said relationship and to say that “oh yeah that stuff happens and you’ll move on” is absolutely devastating to me this is THE LOVE OF MY LIFE and your telling me that iv been lying to myself this whole time or that I didn’t realize?!?!? And that sexuality can change (even though some say it can’t google says otherwise and some people have said it can’t idek anymore) and all this other BULLSHIT I can’t take it WHY?!?! why does this have to happen why can’t I just be with my love the rest of my life?!? and yes before anyone says anything I have been attracted to girls more so when I was younger watching lesbian porn liking the body’s and fantazing them sexually it stopped when I got older but I still don’t get disgusted with women who are pretty it just makes me uncomfortable because I’m with the love of my life and before I remember talking to my partner and discussing certain childhood things I experienced and we discussed that we both could be a little bi and for certain I’m (demi sexual so I don’t even really care about looks) and I truly didn’t care!! NOW I do care even with being bi because again I don’t like thinking about anyone else but my partner but I do also know my parents are homophobic and I do think about if I am gay they wouldn’t be okay with that and I also dont want to deal with that so now I sound like in indenial right?!???? I didn’t even care about labels before my ocd it just didn’t matter but now it’s effected my sex life and it’s hard for me to enjoy sex with being so confused I’m so confused I googled everything can you still have sexual fantasies with same gender but still be straight? Can you fantasize about same gender or imagine marrying them all of it !!! And non of that disgusts me it just makes me uncomfortable AGIAN only bc I just love the partner I’m with right now!!! I’m so fucking confused do I have to leave my partner and accept that I’m gay is that going to happen in the future if I get better with ocd and find out it’s been true all along?!???

for me it’s getting to the point where i don’t feel in love with my boyfriend anymore. i’m trying to keep myself from compulsing since my compulsions are all mental. it’s like the thoughts consume my mind every second of every day and i can’t catch a break. it’s like i want to be with him so bad but my brain won’t allow me. any advice?
