Robby,
When I was 19, I got married and it lasted 10 months. She was pregnant when we got married and it was pretty much the same type of thing. She left, took the kid and headed for her parents.
I accepted it and just wanted the divorce done. DON'T MAKE THAT MISTAKE!
I let her take everything, a house that was almost paid for, the furniture and everything else.
My sister took her to the city where they had a good ol' time on the credit cards.
By the time they got done, I was $20k in the hole and I was a mess.
Now, that may all sound bad, but the good thing of it is, the gal I am married to now, we were going out in high school and we'd have hooked up, but trips to Alaska and back irritated her. Anyway, my other sister got us back together after the divorce and we've been married for 16 years now after a few years of just being together.
My point to this long winded BS is, some things happen for a reason, while it may not be clear and evident.
I hope the best for you.
