Husband hiding alcohol

For some context. I (28F) and my husband (28M) have been together for almost 7 years. We have two beautiful so sons.

He has always been a drinker, drank every night, but it never bothered me because he was never mean or violent.

That all changed last month when he hit me In the face and choked me. I left.

I came back, because he promised to get sober and go to therapy.

He made one therapy appointment, but never went. He said it was because it was too expensive and we can’t afford it right now.

Yesterday I found three empty off brand buzz balls in our trash bin outside. He lied to me three times before coming clean about it.

All my trust in him is gone. I don’t know what to do.
