I'm in desperate need of help! I have a great girlfriend but my ex-girlfriend and his new boyfriend constantly plague me. I literally stalk them, unable to let go. I have tried any means possible to learn about what is going on with their lives and I just want to move on. I'm a twenty-one-year-old grad student in chemistry at Columbia right now and am on my break, so I have ample time to brood over this issue. Please help me get over this obsession!
