I think you should stick it out with this 'girlfriend'.
I mean.. so what if the separation has lasted 4 years and he pays zip for child support. The divorce has to be around the corner. It's not like she cares for him or tries to help him out when he's in need... well, except for those pesky debts she pays off for him. And after a month of knowing you, she's driving your truck and you've given (note: not loaned) her money. I'm sure that waiting until the end of the month will resolve the issue.
After all.. you don't want to break the heart of someone you just met, who needs you so much.. and finds you so honest and all. And wanting to have your last name? Isn't it just $50 to change a name without having to deal with all that bother and commitment of a marriage? Oops... wait... after a finalized divorce.. then marriage.
Remember.. toreadors are not the only ones to wave red flags. It all depends on what you're looking for... and/or... at.
