It's her grave she's diggin man... You can see the writing on the wall...
Imagine this was your daughter and she came to you and told you
"There s ahot guy at work. I dont' know him but I am gonna ask him to let me move in with him."
I imagin you would tell her she's a damn fool yes?
Just throw away that phone number and don't follow in your wife's footsteps... she's headed for trouble and will kick herself one day and you can have a sad chuckle at that time.
How do we know this guy isn't gay, in a relationship, or wants a bachelor pad to sew his wild oats on a different young woman each night...
Guys that young like their space... I can imagine a hundred reasons why he would say no.
