Husband doesn’t want me

After 5 years of marriage my husband told me and this family members who were trying to help us work on our marriage he doesn’t want me and wants to divorce me. They explained to him divorce wasn’t the only way to fix a problem and he said nothing they said would make up his mind it’s been 2 weeks his supposed to finalize the divorce he hasn’t. We have 2 beautiful little girls who love and adore him but he doesn’t care for them. I’m just sad and lonely I don’t know how to move on his on a dating website I tried to cat fish him by pretending to be someone else and he messaged me but asked me if I wanted to smoke with him it was weird I thought he was looking for a relationship. But I’ve messaged him and called him so many times just trying to talk to him and see if he really wants to do it but he doesn’t respond nor answer my calls I don’t know what to do anymore I love this man. How am I supposed to move on? Where do I start? How do make him see his making a mistake? Please help me!
