Feel all alone 😔

Am 24weeks2days, I have my other half but I just feel that it’s not working out with us, wee fight and don’t talk and I don’t have anyone else,he has ocd and it’s driving me mad and I just can’t cope with him round me,when I tell him I need a day to myself he tells me how much he loves me and how much he cares for the baby, but he just doesn’t understand what he’s doing wrong... I tell him over and over but he still can’t understand what am trying to say to him, I don’t know what to do... if I leave him he will do something silly.. because of his ocd.. self harm or something.... but I just don’t feel happy round him, what should I do 😭😢😭😢😭😢😭😢 please help xxxx I just can’t cope xxx
