My ex disappeared off the scene about 6 weeks after my now 28 year old son was born. I allowed access but he was totally shit and saw his sporadically until he was 3 and then started sleeping with my best friend and that's probably the last time he attempted any contact. I was only 16 when we met and a young mum.
My DS has decided to contact him as he knows he (DS) has two siblings and although I appreciate why he wants to and I'm obviously not objecting to it, I can't stand the fact he's doing it. My ex and his family have made no effort to contact me or DS in 25 years plus. They're totally toxic and pathological liars. I was left to raise a child when I was still a child myself - although thankfully I had support from my mum and went back to college / university.
I don't trust them and I think DS expects more than they'll offer him in terms of how much interest they have in him.
Arrrrgh I have to let him do it but I so wish he wasn't. I feel oddly rejected. Anyone had an adult child seek out his estranged family and it not ended in a total shit show?
