I need some advice on an issue I'm having with my girlfriend at the moment. We have been dating about a year and things are really good. Early on when we wfirst started dating we talked about our pasts a bit. I'm a single dad so she had concerns which was fine. She also told me about her dating history as well. There was individual, we will call him Joe, she would bring up from time to time that she considered one of her closest friends, in fact she went out of her way to point out that nothing ever happened between them. I asked her on one occassion early on if they ever dated and she said no reaffirming that they were always just great friends. At one point she even attended one of his personal training classes, I thought nothing of it as she always said they were friends. Well as time went by we decided to plana trip to the Jersey shore where she used to live for a few years before I met her. She wanted to introduce me to her friends down there, Joe included. However about a week before we were supposed to go she told me that Joe would not be able to go because his girlfriend didn't want him around my girlfriend. She seemed so upset about why this girl would over react like this, after all she and Joe were never anything more than really good friends. I pointed out that Joe's gf most likely felt this way because she believed Joe and my gf were an item at some point. My gf again flat denied a sexual relationship...friends...really good ones and thats it. We never talked about Joe again after that. One night while I was at work I ran into a girl I've known for a while who also knew my girlfriend from the shore days. She told me that my gf was a great girl and that she used to date a friend of hers. I asked who it was and she said Joe. I confronted my gf about this and got her to admit to dating him very briefly...that they were friends that decided to try to be a couple and that it didn't work. They only slept together once according to her. When she attended his PT class she didn't even speak to him. While I understand everyone has a past I couldn't and still can't figure out why she would lie about this guy in particular. She said she didn't want it to be awkward when I met him...that it was so insignificant she didn't think I needed to know. My belief was if its insignificant why lie about it. In any event I ran into this mutual acquaintance again and asked her how long my gf and Joe actually dated. She told me they dated for a while, over a year, and that it was pretty serious. I have yet to say anything to my girlfriend but I'm having a hard time accepting this. I get that its the past but I can't understand why she'd lie about it in the first place then continue to lie about it. I'd like to see what people's opinions are of this because it really bothers me. Really appreciate your opinions. Thanks so much
