So, I live with a girl, who has been my best friend for several years (i am a male). She is 19, I am 22. We rent an apt together because it is decent neighborhood close to college. My roommate has dated a good guy for about 14 months, and he lived with us for about the past 11 months. Lately, he has been kind of a jerk, and on Friday she asked him to leave for a while. Today, he made some comments to her about how he "was going to get her back, just you wait and see", so we packed alll his stuff and he is pretty much done here and she is done with him. I love this girl in a friendship way, and I support her in what decisions she makes as long as she is happy. Since she kicked her ex-bf out, she has been messing around with this guy we know from across the street. This situation is causing me to not be able to sleep at night, hence I am up at 4:30 am right now. Supposedly he is funny to her and he helps her take her mind off of her ex. What is looks like though is that she is sleeping with this guy, who is 32. It tears me up to see this girl mess around with this guy as a way to escape her emotions about her breakup, and I just dont know what to do. Tonite they both came drunk over here and made a real ruckus for a while, doing who knows what, but its not hard to guess. I think that although nothing serious willl come of this, I worry about her because this type of activity is not typical of her, and I know she is just going to get hurt. Additionally, this guy has been around the block in his days, and I worry that messing around with someone like this is very risky. I and she both know that he has had at least one one-night stand with another woman on our street. I am worried sick about this, but I just dont know how to confront my friend about this without coming off as jealous or trying to be her father. I have gone back to drinking and smoking, two things I hate myself for doing, I just cant cope with this, and the only other person I really can talk to about this just arrived home from Italy, and she is sleeping off 26 hours of travel. I just need to vent this, and I hope that you can take this seriously, I am pretty much new to the Asylum, but I hope that you can share your thoughts. If you can help me, I value your advice and kind words. Although I do not see this girl as someone that I wish that I was dating, I care the world about this girl, there is nothing that I wouldnt do for her. Its just hurts me when she rejects her true friends and trys to numb her emotions with what she is doing. Thank you in advance for your support. edited to add: the ex is a spineless coward, he wouldnt ever actually try to get anyone back, so that is of little concern to me or her.
