I have a very unhealthy relationship with someone, and it's been going on for 4 years. It goes from really great highs to really bad lows in no time.. and I think it's okay because those highs make me happier than I ever am any other time, but then the lows put me back into depression. Right now is a low. I know it's a bad relationship and I should just cut him totally out of my life.. and I have before in the past. I have gone several months without talking to him or anything, but I still think about him and miss him and crave talking to him and give in.. because I can't imagine my life without him. I don't know what to do to just get over it once and for all.
