IMO, the story is one-sided. Well, you have mentioned everything about you and the girl, but you failed to mention about your WIFE and your kids. You are talking about your future. How about theirs? You failed to mention the AFTERLIFE of the other people involved in the story. Please consider that their (your family) involvement in this story is a result of your decision before you got married.

this will be a big mess you are getting into.
