The beginning of after

I feel lost. I'm breaking down. I feel like I'm dieing. There's no reason I should have to feel like this. I don't know how it happened and I'm crazy to find out the real reason why. Shane and had the perfect relationship just a few weeks ago. We could laugh and we're perfectly compatible. We just understand each other. Then he starts this hardcore jealousy thing. And out of all my past boyfriends who have had a reason to be jealous, I am more faithful to Shane than I have been to anyone. I've given him no reason to doubt me. Yet he refuses to let Taylor go. 

I've tried telling him there's nothing to worry about. But he refuses to listen. Its like he's stuck thinking I'm like his ex's who left him to be with their exs. But that's not an issue with me anyways. Then he's threatening to leave me and I feel damaged. I went our whole relationship without jealousy issues because I've trusted him wholly, and now I feel like that trust is gone. There's girls popping up that are more concerned for him than they have ever been, his boss included. He's been going to parties without me, when he normally always invited me. Even if it was only to show me off. He knows I hate his friends because they're not exactly friends (even though he swears they'd do anything for him, but where were they when he needed them?) and they sleep around and do drugs, why would he even wan to be around that.?

And then he adds that we haven't had sex yet!? How low can a guy get? I understand that's all they think about but then he goes on to say that I need to get rid of my rules (my morals) and just be physical with him. And that he doesn't want marriage or kids or commitment. What happened to my boyfriend? Who wanted 6 kids (5 boys to remake the Tracy's and a girl to spoil)? And a house in Arizona with a dog and cats and all kinds of happiness? It's gone. I'll do what I have to to keep him. But will the trust ever come back? Where have the Unicorns gone?
