get over it. seriously.
it's a good sign that she won't go loopy, psycho stalker on you after you split, that she won't bad mouth you or try to screw you over.
why should she stop being friends with him? just because he's seen her naked and you don't like it??
women talk to their bbf every day. you don't own her. quit whining and enjoy her!
The advice is get over it and just be happy with what he has? I disagree. The situation is obviously a problem which is why it was brought up, you can't tell someone to be happy and simply accept a situation that is upsetting.
Drifterwood has it right, if this is getting in the way with the growth then there is a problem. Daily calls and nightly chats is a bit excessive in my opinion. Communication is the key so I would bring it up it calmly and assertively to let your true feelings be known and find either a solution or glean more info as to why there is so much contact.
Good luck
