Is he cheating?

I got a couple of phone calls recently from a girl that I dated before my current girlfriend, and I told her about them. I won't say she was happy that I talked to my ex., but I didn't hide it from her. That's when it's cheating; when he hides it.

Did he tell you that they were talking? If someone hides another relationship while in another relationship that is a form of deceit. If he is not openly telling you, his girlfriend that they talk? Then I would have concerns about it. Ask him if would be upset if the table were turned. gotta keep your eyes open. I can't believe she had enough nerve to ask for him when you answered the phone. But, some girls do not care. Just be careful.

This is an assumption, but with the only knowledge you gave us.. yes.

Do you work during the day?
Does he work?

If he does, get his schedule. Then call your house around the time he should be home.If he is everyday then he may be okay. You could always ask him but that's not that smart. Why didn't you tell her to go screw herself and never to call again.

And tell him that it isn't like he can't block her number. All you guys have to do is call the company and they have to block whatever numbers you want to!

Did you ask him about her? Like why will he talk to her later.. that kind of stuff?

But don't turn into a person that is scared to be cheated on and really jealous, he will leave you if you start that and you are not like that already, trust me. ;)
