Renee, His comment meant absolutely nothing....they say things off the top of their heads and nine times out of ten they mean absolutely nothing to us and they don't always remember what they've said.
I suspect his comment was a projection as to what he's done. In the back of his mind that maybe you will find someone else and leave him alone and yes, appease the guilt he feels deep down for what he's done to you. Please try to stop analyzing every word he says or his actions...they will make absolutely no sense to you, but to him they do. Why? Because he's the one that left and has issues to deal w and until he's willing to talk to someone about them, he will continue to run and make the same mistakes over and over again. You cannot help him.
You will never be able to figure out what he means or why he does the things he does....if it is a mlc, they do things based on emotion, not rational thinking. Go back and reread the threads, for we have talked about this over and over again w/others and yes, in the Archives as well.
Keep the focus on you and the two young men living w/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.
