HELLO!?! Do you know nothing? It's because she still likes you, or has feelings for you.
Open your eyes. If you can't do that, then you don't deserve her.
Because they want to get back with you.
It means the ex boyfriend still likes the ex girlfriend.
because this preson still has feelings for his ex-girlfriend
My guess is he still likes you.
maybe he wants you back.
Its not an ex-girlfriend. Maybe he calls for a bootycall
To find out what to buy you for your birthday present.
My answer depends on if you and your ex wife are still friends...If you and your wife are still friends then you need to calmly explain to your girlfriend that you were only joking around with your exwife and tell her it meant nothing. If you and your exwife aren't still friends, then i really don't understand why you would even begin to think it was okay to call her baby, and as far as I'm concerned about your girlfriend, i would be mad too.
if your Ex-Girlfriend is calling, answer, but try not to act very "can we go out again." Just be yourself, but don't have this phone call get in the way of another relationship. Remember that you two broke up before.
Either she still has feelings for you or she wants to be friends.
Either she still likes you, or you haven't asked about them
You don't, but if she is then that is her problem. It is your ex-girlfriend, you should have moved on.
