I have a daughter who is 7 and who I haven’t seen in 18 months. I miss her very much. Her mother has launched enough cases on me which can put me behind bars if proved. All this so that I give up my rights to my daughter.
But if she was 18 and does not want to see me, then I can’t really do anything about it. Same goes for your son. If he wanted to keep in touch with you, he would. There are no cases that your wife can launch on you which would have any damage on you. So stop cribbing and accept the fact that your son does not want to stay in touch with you. And this blind father and his house story is just a sob story.
There are enough people in this forum who need serious help. So stop wasting your time and face up to your life, because no one else is going to do it for you.
