I don't want to give up...

I don't want to give up on my husband I really don't. He's an alcoholic.. We got married 2019 we both went to seek help on 2020 I had a very bad depression and he went for his alcohol addiction..... We went december 2020 he stopped drinking... Drank again this year on July and its way worse than before pregnant again... I am so sad I hate seeing him like this sometimes I get upset but I realize how his addiction took over him and I just want to cry he's drunk at the moment and he told me he loves me but he loves drinking... A few weeks back I told him I miss us when we use to go to the group that helped us and he said he never wanted to go that he wasn't being him self that shattered me....now I don't know what to do to help him... I feel like maybe it's because he's drinking again he feels that way something in my heart tells me he can change... I don't want to leave... My heart is broken...
