Hey all I have a problem in my relationship.
Firstly I'll just tell you the background... I have known my girlfriend for about 4 years we went to high school together and after we kept in contact we hooked up about 4 months ago and since then things have become serious very quickly! Anyway the problem I have is that I am one of the most jealous guys I know. I am not proud of it and I really don't know why I am this way.
My girlfriend has recently started going on nights out with a group of her friends the majority of which are guys, occasionally she will ask me if I want to come but knows I am not a party person. Now back on track... one of the friends she goes out with, she is particularly fond of, she talks about him quite a bit and they often IM and email each other. The other day I also noticed that the wallpaper/background picture on her cell phone was of her and him! And needless to say this got my jealous juices flowing, but I tried my best to remain calm and forget about it. She told me last night that she was going out on a work party but when I saw her today she said that she ended up meeting this guy at a club after. When ever I tell her how I feel she thinks I'm trying to cause an argument and falls out with me!
Does she see this guy as more than just a friend? Or am I the one that is blowing it out of proportion?
I work as a police officer and in the new year I'm transferring to a new police department which means a 300 mile relocation, I wanted to ask her to come with me but now I'm not to sure.
Please can someone give me some advice!!

I think she sees him as more than just a friend. I'd just relocate and forget about her. She's too much into this other guy fro her to be into you the way you want.

Hey yeah thanks.. this is what I though myself I guess I just wanted someone to confirm it for me.
I spoke to her last night and in the nicest way possible I told her that what she was doing wasn't fair on me and that I had to concentrate on my career... anyway the first thing she did was ring this guy and let him know! Says it all I think!
Thank you so much for your help s_cianci I appreciate it very much.

Sorry you're going through this. That's horrible that she calls him right after you tell her what she's doing isn't fair...
Remember that the last impression is key. Be very strong and leave her. Don't be mean and don't be nice. Just leave as a mature adult and wish her luck. If you don't cry for her and you don't chase her, she'll get confused. That is, give her something to think about.
