7 year relationship

Hi,

i don’t know where to begin…. I have been with my boyfriend for 8 years. We have talked about marriage, family, getting a house, over all building a life together. But we are still only boyfriend and girlfriend. We do have a daughter together she will be 6. We have been in the same one bed apartment since we have lived together in 2015. We have communication problems, he’s an alcoholic, I suffer from depression. I have a hard time showing affection. he has cirrhosis of the liver. He would always leave me at home with the kids and he would go out with friends all the time. We have broken up like twice in the past where I left the house but ended up coming back. Not giving myself enough time to think about things Bc he would always call and tell me things I wanted to hear and I would come running back. About a week ago I went through his found and found he was looking for prostitutes. He swears he’s never done anything or ever cheated on me. So now that we are in this present problem he’s calling me telling me he is going to change his ways a be a better person. That things will get better. Idk if I should continue and act like nothing has happened. I don’t feel happy. I feel like my heart isn’t in this relationship any more and I don’t know what I should do. I don’t know if I should move out or continue to stay with him.
