My Children And My Marriage!!

Dear Readers

I posted a while ago about finding out my husband was unfaithful. I decided at the time that I would try to work it out with him because I loved him and because we have three children together.
Well I am here 2months later and he is acting suspicious again. I don't even need evidence. I've been married to him long enough to know when he's hiding something and lying straight to my face. I feel so very done. He tells me he loves me and I cant even say it back. He watches to much porn in my opinion and then expects me to reenact what was visually stimulating to him. But they are things that I find utterly repulsive. Don't get me wrong I like kinky fun sometimes to spice things up but he wont have "regular" sex anymore. And he never ever "finishes". So while we may have sex once in a while there is NO intimacy. I feel like its impossible for me to be for him what he desires me to be. I know he resents me but when I try to talk to him about anything he tells me I'm reading into things to much and need to get over myself. We've stopped arguing and have become indifferent to one another.
So here is my question.... Do I stay or do I go? My children are so in love with their daddy, a divorce would devastate them. I am not happy. Even typing that I feel selfish. Do I honor my vows despite my feelings and despite the fact he was not willing to keep his vow to be faithful. I don't love him anymore I actually cant stand the sight of him. But that being said I know Love is a choice so do I just wait for my emotions to catch up to my choice? Is a marriage worth saving when only one person is trying to save it?
