Wanting to move out and leave my husband

Sometimes love isn’t everything we been married for 2 years we live together but I want to move far and pretend I never met him I have felt hurt a lot and cried so much. We have lived together with my grandma because he has said he is not ready to move out now I’m making enough money to move I tried to work it out I told him let’s go to couples therapy he said it wasn’t necessary he is in denial. I feel like I maybe I still might love him but I resent him a lot because he changed he is no longer affectionate as before. He says he loves me but I told him I want a divorce and to leave I don’t even know where to move too but as far as possible from him we got married young yes I’m 21 he is 25 but as time has gone on I feel like I no longer feel the same as before I don’t feel as happy as before I’m bored in this marriage. Barely sex we only do it once a week we are no longer sexually compatible I told him that I’m sorry but I’m young and need someone who could give me what I need. I can’t spend years with someone who no longer satisfys me sexually as much as I need and I use toys but I want a man to do to me everything that he doesn’t do to me in bed. Ive even felt like I hate him and I’ve told him that we both have cursed each other out and he says it’s not his fault. I want to forget about him I want to move far away and pretend I never met him. He refuses to get a divorce.
