So my boyfriend told me he was cheating on me in mid september. He said he wanted an open relationship. I immediately broke things off because I believe in monogomy and couldn't handle the betrayal. That being said however, it is now almost December and I still can't get him out of my head. I think about him all day long. We have spoken on and off but haven't for the past 2 weeks. We were together for 1.5 years. I don't know how much more of the anger and the missing and the overall sense of loss I can take. This has been one of the darkest times in my life. IS there any light at the end of the tunnel?
