Marriage

So been with my husband for s for 11 years we are both 28 years old and married a year. Since getting married my husband changed he says he loves me but doesn't know if this is what he wants nd is out a lot drinking instead of facing reality. He was due to leave but changed his mind saying he wants to stay living together and take the emotional side out of it nd pressure nd who knows we might get back together but can't guarantee it. I don't know what to do apart of me prefers for him to just go and I can move on but living under the same roof is going to be torture did anyone do this and get back together with there spouse??
