You are absolutely wasting your time, Monk--Don't even think twice about this one. I can tell that the only reason you think it's a good idea is because it's a sort of safety net; you've had something in the past and she seems to be suggesting that there's a possibility for something more--it's the easy option, maybe even your only option right now. But let me tell you, she sounds like she's walking all over you, put a stop to it right now. Tell her she's a cheating bitch and needs to get her priorities right before she can even start shining your shoes. There are roughly 3billion women in this world, to chose someone who is basically using you to make up for their own self-esteem issues is not healthy, people like these are only a drain on your resources, they contribute nothing. Surround yourself with positive people, don't become some stupid bitch's coping mechanism.
