I think we should all pay Ali for her services, she did mention that Friday is a breakthrough day, didn't she? And she kept saying this week may bring changes...
No, not all, yes, text him thank you and even call him while he is at the house. I got the feeling from what you said that he is worried about your behaviour. It was nice you were ubpeat and friendly then and IMO you should try to get across to him that you are OK with interactions, so that he loosens up a bit and feels relaxed to at least start on a friednship...
Good Luck, I am happy for you, make the best out of it!
