Not blaming addiction but it's very clear he has addiction issues. My only point was people coming in saying he's full of shit and he's lying and he's not sorry or he's only sorry b/c he got caught. I don't buy that. It's entirely possible he's sorry and feels terrible (I'm skeptical, but it's possible......) when he's drunk/high he does shitty things and then he feels bad the next day. IT doesn't excuse the actions, he's responible for them but to say he's faking being sorry.........we don't really know.
The biggest red flag in all of this.....what kind of self respecting woman (or man) stays engaged for like 9 years or however long they've been engaged. Either get married or don't.
