Should I (18F) ask my boyfriend (20M) if he accepted another girl’s friend request?

I know the title might sound a little controlling but I just needed to vent this somewhere and ask for advice. My long distance boyfriend and I have been dating only for nearly 3 months now.

So today he got on social media and told me that he received 4 friend requests from random girls. I asked if he accepted them, and he said no. Then he told me that another girl sent him one, and I saw that he accepted it since that girl and I now have him as a mutual friend.

It just made me wonder what made this girl different if he rejected the other 4 friend requests? I admit I can be an overthinker so I thought that maybe it’s because of her profile picture since it was of herself and honestly she looks gorgeous! She seemed like a kind person too so I have no hate towards her whatsoever.

A part of me also wants to know if he’ll keep this from me..? If I ask, will he say that he did accept it or just say no to keep me from wondering? A larger part of me trusts my boyfriend, and I guess this is the only time I can verify things (because we’re in LDR) since I have evidence of something, compared to just believing what he says.

I’m completely fine with him having female friends as he has them from previous years. Never would I ask him to cut them off. It’s just this one time that’s bothered me a bit and I have a feeling I might be reading into things too much again. He’s joked about getting with other girls sometimes and we’ve had a talk about it. Ever since then he’s stopped. The urge to ask him has somewhat worn off and I kinda care less now if he’s accepted it or not. But a part of me still does want to know and I should be comfortable asking him about these things?

Should I just go ahead and ask him? Or is it too much?

TLDR; my bf received 5 friend requests from other girls he doesn’t know, and rejected all but one. should i ask him about it?
