Ok, I think this is going to be a long story so... sorry in advance. I've been in a relationship for 4 years now. We have a 6 month old daughter, and we argue all the time. Our sex life is pretty much completely shot, and I always find text messages in her phone to and from other guys. One of which said "I'm going to take a bath, too bad you can't join me". I confronted her about this, and she said it's a kid she used to go to school with, and it was just a joke, she wasn't serious when she sent it to him.
Anyway... I obviously suspect she's cheating on me. So I did something probably kind of stupid. I made up a name, and an e-mail address and started talking to her as that guy. I've been talking with her for a while now. I recently started saying that we should meet each other, but said if I meet her, I'm going to kiss her. I was happy when she came back and said no, that she won't kiss, or do anything with anyone other than me. Today we're talking and I again brought up a kiss and she said no. So I started asking her personal questions, like weirdest place she's had sex, weirdest thing she's done having it, ever had 3 some, fav. Position etc. She answered all of the questions and even asked a lot back. I even told her that talking about it was kind of turning me on, and she put a smiley.
Should I be worried, or is it just normal for women to talk like this to guys? I know making someone up is really childish... but I guess I had to know, and wasn't sure if she was lying to me or not, it was the only thing I could think of.
