Is it normal that my boyfriend is still best friends with two of his exs?

Tough call. I dated a woman who was still very tied into her old high school friends, all guys, and in close contact with several on a daily basis. I knew one from the sports bar I go to, and, even before met her, didn't like him for many reasons. Once I started seeing her, this guy got involved, pissing me off. I told her, I'm with you, not him, to her standard answer of "We're just fri-ends, I grew up with him".

Ok, then..How did he get my number and text me? If not from you (which I knew he did), is he some sort of magical cell number guesser? While he was the only one who texted me, she remained in close contact with several others, all stated as "fri-ends". Yeah, and more than one posted online about "still holding a candle" for her.

I do believe her that they're just friends who grew up together, but, to be honest..I still hate that she and the guys are so connected, nearly every day. I'm with her again, btw, and that aspect hasn't changed.

Thing is, I also have several female friends, and friends-only, so am not in position to rant or go off on her, as she can say the same things to me as I would to her. Just have to play it by ear and try to trust the other person. I know it's hard, but it's the only way. If you don't trust them, it's as good as over between you two.

What you feel is absolutely normal. Many people feel this way. But does it concern you if he talks to his other girl friends? If not, then it's more about you being insecure than his talking or hanging out with his exs.
Think of it this way, an ex is like an old friend. You have a history and a connection. If you are able to maintain that even after breaking up, without crossing any boundaries, I don't think there's anything wrong with that.
You just need to trust him, be sure that he'd never do anything that he's not supposed to. As long as you can do that, irrespective of what the other person tries(if that is even the case), you don't need to be worried.
Everyone needs their space and accepting that is the key to a happy relationship.
Just trust him and let him be. If it helps, tell him you find it a bit uncomfortable, but you trust him and hence, wouldn't want to intervene. Also, if possible, ask him to try not to do that when you two are spending some quality time together. Keep both of your phones away and just enjoy each other's company.

I personally think it is normal. I am also talking more to my ex girlfriend a lot more than I talk to my girlfriend. I have nothing sexual for her anymore, it's just that she is really good at chatting and we have the same "style". My girlfriend is a better match so I'd not return to my ex, but my ex has such a great sense of humor and this is what connected us in the past. My gf is also talking to her ex, but I believe this is normal. I shouldn't worry about this. If this becomes sexual, it probably means that our actual relationship is not strong enough, so it should break anyways. If you love someone, set them free and see if they return to you. I would talk to him more about this, so you can understand exactly why this is happening.

I personally think it's weird of him.

That's hard to say, personally I'm perfectly fine with my partner being good friends with an ex shoot they can go out drinking together I dont care. I would never date someone I didn't fully trust and I fully trust my boyfriend so he could be besties with his ex for all I care, however it sounds like you do care and if he's not willing to talk about something that's affecting your feelings and such it may be best to let him go
