Loosing feelings for bf?

My bf and I have been together for about 10 months now. Before we started dating, not too long ago, I approached this guy (I’ll call him A), dm’d him cause I found him cute - nothing happened (like nothing , we didn’t even talk for more than a day & didn’t even meet up) which I was fine with. Couple months later I found my boyfriend.

Earlier this year, A would reply to my ig stories a lot, I wouldn’t say much cause it felt wrong to do it & I knew my partner wouldn’t like it, and if the roles were reversed I wouldn’t either. One day I casually mentioned to my bf that this guy messaged him and we spoke - I felt so guilty even tho it was a work related, casual & chill conversation with A (we did not flirt or any of that) and I just didn’t wanna hide it from my bf. Obviously my bf wasn’t happy about it and kind of held it against me a little. But we worked through it - it was fine.

Couple weeks ago I got to know that my bf has friends who are girls at school and they talk every now and then - I told my bf that if he’s gonna have friends who are girls then It should be okay if I have guy friends, cause if not then that’s just double standards.

Lately A has been messaging me and for me it was super casual and friendly (pls note: we do NOT flirt with each other at all, it’s chill conversations like nothing weird lol) until very recently I’m confused as to if I’m starting to get feelings for him or if I’m just liking getting the attention that I’m not really getting from my bf (he’s an engineering student & he’s insanely busy).

My bf and I have been through couple rocky months, my therapist feels that because of this, it’s normal for me to feel this way (confused) because of the fights and arguments we’ve had.

I feel bad to even question my feelings but I’m not sure what to do from here. I’m going to stop talking to A for sure... has anyone been in a smiler situation? Does anyone have any suggestions/recommendations as to what I should do from here ? Thanks in advance xoxo !
