<human>: My girlfriend and I have been going out for about a year and have decided to move in together. The move is supposed to be this weekend but we are waiting on the previous tenant to coordinate the move in. My girlfriend said she had emailed him but not yet received a response.

She said that maybe she had got the email wrong so I checked her email to make sure she had the right address. Sitting in her sent box (along with the email to the tenant) was an email to her old boyfriend asking if he wanted to meet for drinks this weekend (she initiated the conversation). I was a little dumbstruck as this guy had cheated on her in the past and I thought she wanted nothing to do with him. They had dated on and off for many years but she said she didn't want to have anything to do with him anymore when we talked about him before.

Foolishly I didn't confront her about it then and there and closed the laptop and we went out for brunch. At the end of brunch I asked her if she wanted to go out on the Saturday (the night they were to meet up) and she said she had plans. I asked what she was up to and she said she wasn't sure yet. I am hurt and worried. If she had come out and just said that she was seeing her ex I would have been upset but we could have at least talked it out, but the cloak and dagger stuff has me worried and my guts all knotted up. 

Moving in is a big step and I was excited, but now scared. Any advice or thoughts would be appreciated.

Can you condense the text into a few key points?
