Thanks Rabbit. I will only be seeing her once a week (while he is still at school) when I drop my son off. She gets him ready for school on Thursdays and I pick him up from school.
I did get there late, and she was waiting for me (it felt nice). I walked in confidantly and she commented that my new sirt looked good on me.
She did get teary a few times last night at different stages and while she was getting teary, she would shake her head as if to say "no, I don't want to hear it" (this would be when I was telling her that her stuff about communication and that I never wanted to hurt her and that I realise why we went wrong)
Even after she got into her car, I was standing at her window, and I said "for what it's worth, I never wanted to make her feel the way she did" and she got teary again. She didn't say anything. I said good night and walked to my car.
