My guy and I have been together for about 2 1/2 years. I am 38, he is 31. We have been living together the better part of the 2 1/2 years. I was previously married for 10 years. He has never been married but has been in at least one relationship that lasted over a year. I don't believe they lived together, but unsure. Anyway, we work out at the same gym together. He belonged there prior to me moving in. When I first joined, he said he had brought other girls there in the past and they felt insecure being there with him b-c they didn't feel confident around the other women who were there. Much to his surprise, I was in better shape than he thought and his friends began to make comments about how I was in better shape than any other person at the gym. Nice fiends! Anyway, there is a trainer who has been there prior to me joining and currently working there. She is 27 and has an incredible body. Big boobs, little waist great butt and no kids haha (I have 4). Anyway I have always called her my nemisis b-c she is the one person at the gym who totally annoys me. I suppose it's the way she walks around all cocky like she is a spoiled princess. Of course she's hot and all the guys talk to her. She had dated one guy from the gym (average guy) and then just broke off an engagement with another guy who used to work at the gym (kind of nerdy). Since they broke up she has gone out of her way to flirt with my guy- from waving REALLY BIG all the way across the room, to talking to him while he is working out and she is training someone. When I see this going on, I'll look at my guy, and he gets this little smirk on his face. I used to say that it bothered me, but now I just don't bother. She was fine while she was engaged, but now it's as if she's waving her arms "Hey everybody, I'm single!!!" First of all, when I am at the gym, I'm very polite and professional. I would never dream of talking to or flirting with another woman's husband. I have many friends at the gym who say that I am very genuine, sweet, and not full of myself. Truth be told, I just can't stand arrogant or cocky people. This person is driving me crazy. Of course I try to be nice to her but she struts around like she's the shi*. At home, I help my guy with his car projects, and even help him load motorcycles and engines into his truck. I don't think princess would ever risk breaking a nail to help him do anything like that. I'm not so much worried that he would end our relationship to be with her, after all we do live together. However, I wonder what I can do to NOT feel jealous. I doubt there is anything I can do to get her to stop flirting with my guy, but if there is, I would like to know. I just don't think it's right for this person to think it's open season on all men (teken or not) at the gym just because she's single. Any advice?
