I really need some advice and this is simply for my own piece of mind to know if I'm being ridiculously jealous or not. I love my girlfriend very much, we live together and are talking about getting married. When we first started dating she told me about her "best friend" she's had since they were 10-years old and later in life were romantically involved.. pretty serious I assume.. Anyway, he lives several states anyway. On Valentines Day I was going to get her a nice necklace but noticed that she always had this silver key necklace on so thinking it might be something significant one of her kids got her so I asked what was the story behind the necklace.. she said her lifelong friend and ex-boyfriend got it for her and that he had a lock that went with it. I don't know if he wears it or not, but the significance was there.. I don't know if I'm being overly jealous or ridiculous but every time I see it around her neck or if she is playing with it, my heart just breaks and it really hurts. She knows exactly how I feel about it and I asked her if she was going to wear it forever.. like when I put an engagement ring on her finger and she said that "the necklace was never going anywhere" it and this "person" have been the subject of many fights and arguments. They talk and text I know probably EVERYDAY. Knowing this upsets me, I will give her credit hat she doesn't answer if he calls WHEN I AM THERE, and rarely texts back WHEN I AM THERE. I do NOT go through her phone but one night it went off, I looked down and I couldn't help but see his text said "Goodnight sweet nurse" All I know it is hurting our relationship and I KNOW, without any shadow of a doubt that now that I am in a serious hopefully lifelong relationship with HER I would NEVER talk to my exes let alone wear something I was given by them. Especially if I knew it bothered her. Maybe I am projecting how I am on to how I "think" she should be to me? Please help!! Talking to her about this does no good. I just do not feel this is appropriate and they both need to move on. In my opinion this is emotional adultry at best.. I'm not saying she NEVER talk or text this person but everyday is excessive. I also know she probably tells him EVERYTHING and confides so he knows how I feel and I think it's very disrespectful to ME by HIM. I think if he truly knows just exactly how much problems he causes and IF he REALLY cares about her and is her "best friend" he will turn his daily attentions elsewhere.
