Feeling stuck in a loveless marriage

I'm not sure where to begin. My name is Hailey and I married my best friend 12 years ago. We have seen our friends relationships fall apart over the years and always felt as if we were the lucky ones. Four months ago, I discovered my husband was having an affair. The worst part is, I found out by looking at his private chats through his facebook account. So seeing the chats was harder on me I think then just the suspicions. Anyway, I threw him out for 4 days. We talked and talked and cried and vowed to make this marriage work. My issue is, even though I know he is trying and isn't seeing anyone, I don't know if he loves me. We haven't had sex since he came home 4 months ago and I want him, I need him. I am a 41 year old woman who loves her husband and desperately wants him to want to be with me in every way. I am frustrated, depressed, and at a loss on what to do. Am I stuck in a loveless marriage? Am I staying to avoid the hurt and loss of another marriage? Anyway I am rambling and just feel so lost.......

Ask him about how he feels about you and tell him your concerns / doubts / worries about everything. You say you don't think he loves you anymore, but why? Is it just because of the cheating? If he didn't cheat on you, would you still think he doesn't love you anymore? Talk to him, let him know what's going on in your mind, only talking it out with him will bring the solution that works the best in your situation.
