Sotto is 100% spot on w/her advice this morning. Relationships should begin as an acquaintance, then friendship and then on to a romantic one. Right now, you are just an acquaintance and that means getting to know him again, i.e., just as he is doing w/you. You may find that you need to explore this new relationship for 12-18 months before anything romantic happens.
Heather, I do not want to see you and the girls hurt/disappointed w/him again. Always remember...patience and his actions need to match his words.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
