Boyfriend only loves me when he’s drunk

So I feel like my boyfriend only loves me when he has had a drink. When he has had a drink he is so loving and affectionate always saying he loves me and that he wants us to get a house together have a family that he never wants me to go home and to stay with him forever I get endless cuddles and kisses yet when he is sober he is always asking me what time I’m going home as if he doesn’t want me there he kisses me sometimes but it’s just a peck and he is always on his phone as thought he just can’t be bothered with me. Its so confusing I don’t understand anyone able to shed some light on what this could mean??
