He’s got a great set up. He’s got his long-term, live-in girlfriend — and he’s got his one-year girlfriend on the side! Whatever he says, the bottom line is that he doesn’t want things to change. If he did, he’d change them. Instead, he’s saying what he needs to say to keep you in the game, and he’s winning at it. Whether or not you’re “the other” woman, that’s really just semantics. What you definitely are is one of two women that he’s with. Instead of wondering why he’s doing what he’s doing, you should probably ask yourself why you’re doing what you’re doing. If you want a relationship with a man who is going to put you first, this is never going to be that. Instead of trying to win him over — which is never going to happen because he doesn’t want it to happen — why not try to find someone who wants just you? It sounds like you’re trying to help him overcome some defect that is causing him to date both of you without choosing. Instead of turning him into a project, shine the spotlight on yourself. If you want monogamy, go get it — with someone who wants it, also. I hope that helps. 😉
