A secret I need to vent

So after my husband cheating I can't seem to look at him the way I used to. The love I had for him is gone. There's days where I look at his face and I caught myself telling myself stop he is not worth it. I become so distance. Sex is not the same..BTW I had him tested for std. All clean. Anyways he won't divorce me or want a divorce. He understand that I have no love for him and our relationship is the same we talk here and there. We make plans as a family, we live together and we are currently moving to a bigger place. But our marriage is broken and for most of it. We are just together for the kids and fear of being alone. Please he says he doesn't want to leave or divorce so he is staying with me. Now as for me I really don't care. I want him around for our kids but the love I had is gone. I don't know if I'll ever get it back. I am hurt, bitter, and honestly tried of fighting for this marriage to work. I did my part to keep it together when I had that feeling I fought for his attention but I quit to easily. Now I am just done. What to do? I love him as a good friend but I don't love him as my husband. He said he is willing to fight for my love until he dies. He will prove to me that I am the only one. He said he will treat me like valentine at night and everyday like it's my birthday. Now what should I do? How can I tell myself to open my eyes and see the new him or open my heart back
