I'm so sorry your going through a hard time!
Has your husband told you why he no longer is in love with you? that's just terrible. One thing I have only begun to realize, is that Taking up your cross and following Jesus was never promised to be easy. In fact , he tells us it will be hard. But know this, he is with you and all the bad things that happen in your life, he has a purpose for them. His own perfect plan that to us we cant even begin to understand or fathom. Our Lord is the best at making something good of bad situations, I promise!
