Partner never comes home after drinking!

So I need some opinions..

Here’s a little history: We’re 23, we bought our 1st house & lived there 3 months so far. In the beginning of our relationship (over a year ago now) he cheated x4 & I got over it eventually as it was in the first few months & it’s stopped now. I do watch 👀 everything so I’m confident it’s not happening.

BUT I told him before we got the keys to our home that if he goes out drinking & doesn’t come home that’s a big NO ❌ from me. That’s not the kind of life/relationship I want in my first home. Since we’ve lived here I’d say he’s not come home like 10-15 times now. He gets in at like 6-7am & goes straight to work. I don’t know where he’s been or what he’s been doing but he says he’s stayed at a friends & I can see on the maps he’s at his friend’s but I don’t know what he’s getting up to there 👀

I’m supposed to be getting my implant removed in less than two weeks to TTC our 1st child & now I’m like, hold-up, I don’t know if this should happen.

Basically what I’m asking is do you think it’s innocent & he’s just having drinks with his mates then going back there & having deep chats or whatever guys do; or do you think he’s up to something & I should worry? HELP!

Edit: Just to make it clear we do talk to each other, a lot. Constantly telling each other how we both feel about it. He feels bad about it but when he drinks he doesn’t know his limits. I also want to add he has body dysmorphia & was addicted to steroids in the beginning but I’ve got him off those. He has body image issues & I wonder if that’s why he’s like this. I don’t want to break-up the relationship as he treats me well in all other aspects. I want to make him stop, if I can.
