Do you have to tell your partner everything?

Hi everyone this is my first post on here but I need advice relationship ocd and ocd in general has taken such a toll on my life as of recently my boyfriend and I decided to not be together we still communicate we’re on good terms and he’ll be visiting soon( long distance) recently a friend I went to school w dad passed and it got me thinking of another friend (male) I used to have feelings for him LONG ago my boyfriend knows of that and I searched his name on Instagram recently and now I feel extremely guilty for this and feel like I need to confess this to my partner did I do something wrong? is this a normal feeling with ocd? someone please give advice.

I’ve had so many moments of clarity with my OCD that I love my boyfriend and I’m beyond willing to go through this to be better and be with him. in the back of mind I’ve in a way known I was at least somewhat sexually attracted to women (I’m a woman) since the start of the ocd it was always like “okay. Fine, but I don’t want to date a girl” I only just realized this after the ocd started, I never really argued with this. my ocd has always revolved around if I’m romantically interested in women and not men. I’ve done so many compulsions through this year and a half and 9 times out of 10 have come to the conclusion that I don’t want to be with a woman romantically. I always end up feeling like I know I love my boyfriend. But the doubts don’t stop about whether I want to spend my life with a woman instead, my heart literally breaks to think of not being with my bf and imagining him with someone else. I don’t want to be with a woman I know deep down somewhere underneath the anxiety that that’s not what I want. It doesn’t feel natural for me, unfulfilling. I want to tell my boyfriend about the possible sexual attraction to women (ik it’s still ocd related) but I’m scared that once I tell him, I’ll realize that I actually do want to be with women and not with him. Ugh I’ve spent hours today ruminating about this after being solid in my commitment with him for a little while, I’m stuck in this loop and idk how to get out right now

Last year I used and app to talk about my POCD and people called me a pedo and told me to kill myself. It has been months and I had even forgotten about it, but I talked about my mom yesterday and I feel a sense of doom now. Like, I could have lived my life normally, but this happened. I feel overhelmed, and don't know exactly what to do, cuz when I stop to think about it, it is something awful, but I spend months just not caring, I don't know what to do, it was not even close to the worst thing that has ever happened to me, but it still feels terrible, it keeps echoing in my mind, and It won't go away, and yes I know it is OCD, I just want to let It go. And I lied somethings to my mom cuz if I told the whole truth she would be even more heartbroken (I just didn't say what app it was and I said it was recently, and not months ago) And I feel bad, but now I can't go back, but if I told her the whole truth, she would've just broke down. Basically she thinks it was yesterday and in another app, and I told her I just commented on something. But I feel so bad! I don't want to tell the truth to her, but also, I don't know...
