Mila, You handled the situation extemely well today. Bravo! He's doesn't understand why you are acting the way you are. He was hoping that you would still be the weepy little lady who would grovel at his feet. In his mind, you should have been right where he left you months ago....not happening.
He's going to make excuses to come by. For example, your d was sleeping, now he'll need to come back to get whatever it is he left behind. Mentioning the lawn? Still wanting to be a part of your life, feels guilty for what he's doing.
It was an emotional day, but you got through it and you dealt w/him and the situation in a very graceful manner. Tomorrow will be better for you.
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.
