I was not really surprised as i realized that she fall in love with him. As she ask me , that he should have a key for the house and he can come and go like he want and i should give him my key (little girls need no key) - i think by myself - she fall in love with him.
Short time later she ask me - oh it was so great when he move in our house - and by the way, you are not more in bedroom (i am in baby room, former guest room). I accept it of course and at the weekend he move in.
She begin to call him my husband - also in front of me and in front of the kids. I am very thankful and happy about this - because that was also the time that i my found my place in the family as little diapered daugther
