How to know if am into women exclusively? And not into my bf

Hey, this is my first time posting, I have relate alot to some postes in this sub, but I apologise if this post does not fit in here…

I (22 afab) lives with my bf (24 m) for a half year now, and dated for 2 years. Before meeting him I kind of thought I was a lesbian for a while, and have dated a few women in the past. Relanships with men always felt reeeally performative, since I would play into the norms of a straight relanships. And my crushes on girls was always waaay more intens, where as my crushes on guys would quickly fade as soon, as I got to know them, or I would mostly just be into the idea of them (I grew up watches bad rom coms with my mom, and always picture something similar for myself? Idk). But this time before I started dating guys again, after getting my heart broken with a amazing girl, I promised myself not to performane, or be fem just for mens sake. And I met the sweetist and really funny guy, whom I now have been with Ever since. The thing is I have started to feel the same again, not like am faking or performantive. But I miss the way it used to feel, and am scared that I got caught up in the attention and the good vibe, I do generally find him atractive and like being somewhat intimite. But idk how to explain it I keep finding women attractive and missing the way it feels to have a romantic cornention with a women. I truly do love him, but I have started getting irritared at him alot, (I struggle alot with migranes at the momentet, which does not help. How do I know if this is just a bad phase in the relanship or if I truly are not romantic attracted to men? Another thing is we kind of don’t match that well in the bed room, we mostly only do hands stuff since we are both tops. Before we met I tried only dating women and only Hooking up with women, but I live in a smaaaaall town, and there is also just not alot of lesbians, so I basicly had to take train for a few hours to even get to Met other gay people, who I don’t already know. So Idk if I kind of just gave up and started dating men again to get reasurence, and he differently desevers someone who is 100% as invester as him. I genereally feel like I really crappy person, for getting the ick and losing interest in some way for someone I live with and who are my best friend. Idk what to do? Any advice Is much apreciated
