<human>: Throwaway, obviously. Sorry, but he's a redditor, and I'm not sure if I want him to read this yet. 

So, we've been together for over 6 years. We got engaged last year and are planning on getting married next summer. Last year was pretty rough for us. I miscarried our first child, and although it was horrible at the time, I feel like we've been dealing with it really well. There's some other crazy shit that happened in his past that I feel is probably a contributing factor to his actions, but I'm not going to go into it online. 

In the past few months though, he's shown some really disturbing behavior. I've found empty wine bottles still in the bag that I've asked about and he says they're empties that he was taking out. The receipt was in the bag and was from that day. I confronted him about it, he admitted that he got drunk that day while I was in class, there was a huge talk about honesty and trust, and I thought we were ok. A similar sort of thing happened a few weeks later. Again, there was a big talk, and I thought (although my trust was definitely shaken) that we would move past it. 

Yesterday I was putting my coat away and I found a can of that vodka energy drink stuff in a shoe. It had obviously fallen out of his coat. I asked him about it and he said that he bought it a while ago and must have forgotten about it when it fell out of his pocket. Sure, fine, I'm trying to trust him, so I did. Today I was cleaning out the shoe rack and I found a mickey of Fireball at the back of the closet. As long as I've known him, he's never drank that stuff. 

I sent him an email (he's at work) saying that I found it and that I would like to have a brutally honest conversation with him when he's ready. I don't know what to say though, that I haven't already said.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Fiancé is lying to me and sneaking alcohol. I don't know where to go for help or what to do. Help?
