Alcohol does strange things. That was one of the main elements of the story. I think drinking is okay, in moderation. Perhaps it is time that you two discussed that. After drinking, I have gotten into some situations that I wouldn't have wanted to. My boyfriend and I still drink, but within a range that doesn't lead to misunderstandings, paranoia, and fighting. I can't say anything about the relationship because I believe this night was more about drunkeness than anything else. Who knows what happened? Perhaps it would be worth considering this through a filter (filter out the alcohol and evaluate the real relationship). Just some thoughts, perhaps not too keen. But, from what I read in your post, this doesn't seem to be the norm for you two.
