Well, keep going there I'd say. He sounds very much confused and maybe the son thing has got him thinking.
You S sounds very intelligent BTW !!! A star in the making.
I would say, keep going as you are, you are slipping in invites for him and he is biting what seems everytime.
Real happy for you, keep going bu ttake it slow and do read to much into it.
(i've also either not read the whole sitch or can't rememeber from all I read, so this is just from the above post)
GL and have a great weekend....
oh, he still came by as he wanted to see you. Ask your son if daddy was using the phone while driving as it's naughty of him ...I.E. did his brother really ring when on route ???
