What would u do?

I completely love my husband we’ve just had our first child and 3 months later I find out he’s been lying to me for months about gambling and alcohol, turns out everyone in our small town knew and would just lie to my face too. I’ve asked him several times to let me see his account as I cannot trust he’s not gambling again, I also asked him to not speak to the same one he’s was doing those things with instead it was time to let those sort of ‘friends’ go. Am I over - reacting? I can’t be comfortable or deal with the issues he’s caused because he keeps being round the same people who he wants to get drunk and gamble with. This is a short account of what’s gone on.

Edit: I have asked him to let go of contact with the people he would gamble/drink with, I get some are impossible due to them working in the same job but to me they do not need to be friends. I had to go out one night and find him for our daughters wipes to which I was faced with him running away using a back door! This pushed so many buttons and it hurt a lot! Anyway what I’m asking is what you’d all do? I’m not sure how to heal? If I can forgive him? Or even work on what’s left of our relationship?
