Frustrated

I just want to vent I don't know what to do. I love my husband and I know he loves me also but he has 1 very bad habit that drives me crazy. He's developed a bad habit of sleeping on the couch for almost a year. I have complained and fought about it but in the end I don't want to force a grown man to the bed. Our sex life sucks also because whenever we try he can't maintain an erection so now I've given up trying . I tell him to go see a dr but he's like how many medicines will he take as he's already on blood pressure medication. I love my husband and I won't give up on him but sometimes I feel like running away from everything. I don't have any friends besides work friends or immediate family where we live either. He on the other hand has many friends. When he was young his father moved out he says he was 5 yrs old so he didn't have any role model. My parents on the other hand were inseperatable. We don't have any children either and have been trying for a while even though Dr's. I had a miscarriage last summer 🙁 through an iui pregnancy
