It's not crazy to ask a boyfriend to stop talking to his ex-girlfriend if its making you uncomfortable. Even if that ex-girlfriend is still in his life, it's not crazy to ask. Don't make a big deal out of it, and don't be angry about it. Just state what you want - "You've been talking to your ex a lot, and I was hoping you wouldn't as much. I know that she's still your friend, but it hurts me to keep hearing her name again and again, and to know that you're always talking to her."
There, that's it. Your boyfriend will know immediately how it makes you feel, and hopefully he'll change how he talks about her, and how much he talks to her.
Since, however, that ex is still in his life, he's still going to hang out with her from time to time, and you need to be alright with that. Hopefully, he won't be spending one-on-one time with her, but they will be in the same place at the same time. If you're not alright with that, then perhaps you need to change your mindset or your boyfriend.
Good luck.

MM, He's not talking about her, he's talking TO her. And to be honest with you OP, asking him to stop talking to her is kind of childish. What are you afraid of? Is he going to dump you to be with her? I know it bothers you that she's still into him but you have to trust him. You shouldn't worry about her and let your insecurities take over. Chill.
It would depend on how often, what situations, and the nature of the convos. I definitely agree with Nice&Sweet that if it's just casual conversations and they're rarely if ever alone together, the OP should relax, they are together, not the ex, and if he was gonna dump you for her, he would have dones so already. Not all relationships end with the exes bitterly hating each other. Indeed, it can be a sign of maturity to be civil with an ex. See if you can talk to your BF in bringing you in the group, that would be a sign of transparency on his part.
Now, if he's engaging in conversations that give the appearances of impropriety or raises questions, she has every right to bring this up with him. But do so in a non-accusatory tone. Nothing suggests he's cheating, but it's understandable you don't want your SO being a bit too close to an ex. Ex-sex is seen as a smokin hot cool thing by our media, which doesn't help the situation.
Haha ex-sex! You've just given her one more reason to worry, Mr.X, lol.
LOL well I presumed that was her concern. Usually is when someone isn't comfortable with their partner talking to an ex.
Agreeing with the other comments here. It is possible to be "just friends" with an ex, even an ex who's still kind of into you. If he's keeping it casual, you're the one who needs to relax. If he's acting shady - lots of one-on-one time, conversations of a sexual nature, etc. - then by all means gently ask him to distance himself from her. If you genuinely have reason to be suspicious of their relationship and he won't do anything to make you feel more at ease, it's probably time to dump him.
I have the same problem! But the girl REALLY still likes him and got mad at him when he started dating me. We all go to high school together, and they both have diabetes. Sometimes when his blood sugar is low and stuff, and it sucks because she understands how he feels and knows what to do to help him all the time. >.
