We were laughing and having fun one minute, then the next I could hear him throwing up in his master bath. I was standing in his living room when I also heard him yelling "F*** You!" at himself and I was immediately on alert. This was a wake up call that this guy was really, really drunk.
The wake up calls/red flags you missed are:
That this guy you have only known for 5 weeks is a great guy! No, great guys don’t show up drunk to meet you in a parking lot with an open beer.
What’s so great about not having a job, sleeping all day and strange behaviors?
You say a switch went off in his brain, that actually means you witnessed the real him in action. This is him, this is how he lives. He’s lived this way before you came along and he’ll live this way long after you are gone.
The only advise to offer is, ask yourself why the switch hasn’t gone off in your brain? Why with all of those red flags would you not be running in the opposite direction?
How can you connect with someone who’s always drunk? What kind of a real connection could that possible be?
He’s not in recovery at all, he’s manipulating you into feeling sorry for him.
Relationships cannot be built on sorrow, pity or potential.
As it was suggested, run fast in the opposite direction.
