I really need some advice. I'm currently in a relationship of 2 1/2years, living together for almost 2. Before my bf and I started getting serious, we had both slept with another person. The guy I had slept with is now out of my life but the girl my bf had slept with just happens to be his brothers girlfriend's sister. His brother now has a baby with his gf which means the sister my bf slept with will always be around. We live in seperate cities from his brother but still tend to go home to visit. Here's what bothers me ... after they had slept together, they still hung out because of his brother. She's a really big trouble maker and crazy. She still tries to contact my bf and it absolutely is sending me over the edge. Its like I will always have to deal with her if I stay with my boyfriend. I have severe anxiety just thinking about her being there when we go to visit. I will even make up excuses why I can't go back home just so I don't have to deal with her. I am scared my bf will go visit his brother without me and she will be there. I feel betrayed if he talks to her but he's the type of person to talk to be nice. If there were me, I'd would not say a word but I know he would talk to her. Our relationship right now has a lot of problems that we are trying to work out .. but I can't seem to move forward because of her. I've told my boyfriend before that she bothers me and he said she's nothing to him and not to worry. I believe him but it's like I don't want him talking to her ever .. or I will be humiliated. Trust is a big issue with us and it's something that I don't have right now so all of this is causing me to stress out. I went through depression a few months ago and seem to be getting better but it's almost like my relationship isn't worth staying in because of all of the negatives.
