She shouldn't as she is your ex - it may have just become a habit for her.
He is trying to be a jerk don't fall for it, he will make you think he still likes you then if you ask him out he with start a lot of crap with it.
You can call him your bgf as in best guy friend
because they want to be more than friends OR is just a way to express a feeling to a kindful friend
of course cause you are beatiful
He likes you more than just a friend sweetheart. Call him boo next time he calls you that and see how he reacts
If the guy gave it to you and told you to call him, then surely it was meant for you, not your friend.
A friend
A guy may call your pretty and beautiful if he only likes you as a friend, but it is more common for a guy to say these things if he is interested in you.
I think he's just a guy being a guy....
Demand it!
special friend
If you are a guy (and straight), then your motives are good and you should. If you two used to be an item, then you should not. You both have moved on and he has obligations that you should not distract him from. Every minute he would spend with you is not with his baby or the mother of that baby. If you still have feelings for him, that is natural and not something to feel guilty about but it is actions you are responsible for. Calling him would be selfish and not good for at least three other people.
They call a girl baby because that's just there way of calling you something sweet
