Agree with DQ. Even if you want her I wouldn't adjust accordingly.....do not get pulled back into her stuff. You have kicked her to the curb in the sense that you do not want the woman that she is back. Think of her as someone you are just meeting that maybe is interested in you, but you aren't interested back. Don't give her the time of day. Continue to just have time for your daughter. No more Mr. Nice guy....he wasn't what she wanted anyway.
So, if you answered, it should have be, "Yes". If you didn't answer, perhaps you should now....by just saying "yes" and leaving it at that.
