Pay no attention to to Mr. Doubt Sofia, it seems he kept the holier than thou attitude of the JWs
Only you can know the right thing to do. Nobody here knows you or your husband, or what you are going through, so it's ridiculous to pass judgement. It's usually best to work on a marriage, especially if young children are involved, but ultimately it's your decision. Some marriages cannot be saved and no loving God would expect you to sacrifice any chance for happiness if that is the case. It's also not necessarily a good thing for your husband if you stay even though your feelings for him are gone. It's possible he would be happier with someone else, someone who loves him as you cannot. That is the hard part, knowing if it's possible to love him or not.
I realize I did my ex husband no favors by staying. In an attempt to be a submissive wife I let him get away with a lot of things that I shouldn't have. He only thought of himself and I enabled him by staying and taking it. Possibly the marriage might have been saved if I had stood up to him earlier on, but by the time I left I couldn't stand to look at him. There was nothing to save.
I didn't make that mistake with my second marriage. We have issues like anyone else, but we work them out because I learned to speak up if something bothered me. It's not perfect, but it is a marriage in a way my first one never was. My husband is my soul mate and best friend and I love him deeply.
