(this is my 3rd AITA question and I've noticed theres so much going on in my life, like wtf)
Okay, so first of all, I've been with my boyfriend for 3 ½ years now, we're a great couple in my opinion and I really love him to the moon and back and he does the same.

There's this girl he knows from his sports club and they're kind of good friends, which I am completely okay with (who am I to tell him whom he can befriend and whom not?). But she has told him that she feels more than just friendship for him. And that's the point that kind of annoys me. I mean, he has turned her down saying he has a girlfriend and she also accepts that but there's still this feeling in my gut. I'm not very proud that I'm so jealous.

I really try to stay calm when he talks about her and I always manage to smile and not say anything bad about it, even though it rips me apart internally. I'm really trying to abandon this kind of feeling, because I know that by boyfriend would never cheat on me and I also know that the other girl wouldn't start anything with him (I've met her in person and she's super chill and friendly).

But the general jealousy will not go away and it makes me feel like I'm being a real asshole about it.
