So my boyfriend and his ex were friends in the beginning of our relationship and I personally did not care until she would constantly blow up his phone especially when we were in dates and always snapchatted him dumb stuff late at night. I told him that I didn't feel comfortable with it because she would start to get mad at him when he didn't reply etc so he eventually unfriended her. recently though she moved to the town we are living in and broke up with her boyfriend, it bothers me because she still sees his family for whatever reason and on top of that literally when I change my hair she changes it to the same thing and recently I dyed my hair black and so did she, she also got gauges like I do. I don't know why she bothers me so much. his other ex's are fine but her I really just want to friend her and talk to her or beat her ass..
