I just want to be happy..

So I been with my partner for 4 years... the last two years our relationship has changed. He is an alcoholic and his drinking has been getting heavier and heavier.. I just can do it anymore growing up I watched my mom and dad fight because of his drinking and drug use. ( my partner doesn't do drugs ) and she dealt with that for 20 some years. And I told myself that I wasn't going to live like that and yet here I am in the same spot... I'm not even happy anymore like I hate being home a d the only reason I stay home is because of my dogs. ( serious dog lover here ). I tell him I'm done with him and his drinking but he just does not leave! Like what do I do? And now with this COVID-19 stuff. Like I cant really do anything... I'm just done I don't want to live how my mom lived. She is so strong and brave I just dont have that in me.. I just want to be done with this relationship ...

I just want to be happy again...
