My marriage is ending..

My husband and I have been together for 5 years. Tonight I think I've finally realized our marriage is ending.

We don't make love anymore. The only time we ever have sex is when he wants it, and there is never any kissing involved.

We barely talk. When we do talk, we fight.

We only say "Love you" to each other when one of us is leaving the house.

He is on dating sites I discovered tonight, talking to other girls. And I should be devastated, but I'm not.. I'm a little hurt, but part of me kind of knew already.. He knows that I know and he doesn't care.

I wanted to save our marriage and work on it, but now I just don't know.. I feel like he has already checked out and is ready to move on..
