How am I supposed to just accept the thought that I Might not like my girlfriend anymore and that I should just break up with her and I'll feel better, I don't want that and even the thought of accepting that maybe I should just makes me depressed

i feel so bad for posting here, idk what i wamt i have so many thoughts abt the feelings i have for my bf im scared my thughts are true or that they will be true and i feel bad for feeling amd thinking this way i such a bad girlfriend, i am scared that i like other people just because i look at them or talk to them normally and i feel like a liar what cam i do to stop feeling like this i am scared

I can’t stop thinking to myself “what if I don’t love her” but deep down I know I love her and that’s why I’m getting pissed off with these unwanted thoughts because it’s putting doubt in my head when in reality I love her what should I do?

Ii spoke w my bf this weekend and he mentioned that he has thoughts just like me, but his don't bother him like me. I then felt a lot better and he tried dissecting one of his thoughts like I usually do and realized it felt more real for him after. That made me realize that none of my thoughts were ever true and I blew them up. However, yesterday I had a thought ab “wait wut if you liked that one guy? How dare you bc youre supposed to love your bf and not secretly like someone else” and treated it as I usually did bc I accidentally wanted to see if it was true but didn't rlly but I would check to see if it was there and now that thought feels so so so real now and I feel really bad how do Ik it's not real? I feel so bad and guilty bc lividly this makes 0 sense but it feels so prominent. It felt pretty real when it happened yesterday too. And now I feel awful bc how is it possible after my clarity the other day? Why does it feel so prominent 😞😞😞
