Alcoholic Husband

Okay I really don't know where to start because I'm just losing my mind at the point.
My husband and I are coming up on our 2 years anniversary and I regret my whole life for not walking away.
When we started dating he was getting help for his alcohol problem and I was so proud of him because he was doing so so good. I didn't know him with his alcohol problem I only knew him since he got the help so I didn't get to see any of the bad stuff.He did tell me that alcohol was his daily routine. That he loved and would go to sleep drunk every single day. It was a big deal getting out of it and he was always depressed that he couldn't have a healthy relationship with alcohol.We got married and here we are about 3 years later. He started getting drunk like once a month and now it's every single weekendI think what kills me that he is so so different when he is drinking. Super sweet and loving me more than usualI know he does love me but it's very different when he is on alcoholYesterday we had a talk about it and he said he loves it and he won't stopI also talked to him about how I feel like he is not trying for our relationship anymore. Every weekend I try to find anything for us to do (event s, concerts, new restaurant, etc.) Anything for us not to stay home but he doesn't try to do anything.He said he loves being home but will also do anything I want to do He also would rather not spend the money on parking and extra fees and being in crowded places.
I guess that hurt me. Are we just supposed to stay home and safe our money until we're old and can't do anything with it.I'm in my late 20s in he is mid 30s and we both make over $200k a year. We both spend money on our hobbies and things we like so why not do things together
I have been hating my life. I don't want to walk away because I love him and I'm scared to death to walk away and start over. I have never loved or trusted someone the way I love him and trust him.
My thoughts are all over and I don't know what to do
