Thank you so much. I appreciate your advice, and I think you're very right. Finding out what the initial problem is is really important to overcome jealousy. Its a very annoying and fatiguing problem. I do sometimes feel like they purposely leave me out because I'm not a fun person, or something else about me. I don't feel good until I find out what the real reason is. Right now, my boyfriend and I broke up, and its so weird that the top reason why I'm okay with the separation is because I won't have to feel jealous anymore about him and his friends going out to parties on the weekend. I think a big part of me feeling like that is because one of the people he always goes out with is my cousin. My cousin and I were very close, until my boyfriend and his other friends began hanging out together. Now, he's more distant and whenever my boyfriend and I had problems and fights, my cousin would only hear his side of the story and automatically think bad things of me. All of this put together pretty much forms a nice pile of jealousy in my mind. Do you still have the same problem? Thanks again for replying and helping out! I'm glad to give my own advice with your issues too.
