what are false feelings? everytime when i think of my boyfriends friend (it’s an intrusive) i’m scared if it’s me being excited or happy over the thought of him or it’s just me being anxious

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 😞😞😞

actual attrcation. i’ve decided im gonna just let the false attraction happen, not try to stop it or question it. is it wrong for this erp to juts when i watch a video and get a false attraction just experience the false feelings and scroll? because i feel like the longer i sit with it the longer i begin to question whether its real or not.

so, my intrusive feelings started over a thought about a guys arms being attractive, and i still think big arks are attractive, but i hate his face? and his personality, so would it still be false attraction? if i like his body but not his face or personality because i have every single false attraction sign, but i just like his arms/body. someone please lmk!!
