Background info:
I have to dc age 6 and 8 from previous relationship (with man who was abusive mentally physically and I’m in therapy for this) I found the courage to leave him 4 years ago. I lived with just me and dc for 2 years before meeting now DP, we then moved into his house after 2 years together (giving up mine plus 90% of furniture) and using this money to do his neglected house up.
Dp has 2 grown up dc, him and his dad do not speak, he and his ds do have a relationship.
He is a lovely man who has helped me throughout the hard time I have had and always treated my dc as his own.
We moved in with him I found a stack of photos on the windowsill amongst these were 1 of a girl on his mother’s lap that didn’t look like his dd, and another school photo of a teenager also not his dd.
I questioned this he told me he didn’t know her name
he then told me she was his brothers
he then told me he had thought she was his but found out his brother had an affair and she was him
that is the story he stuck with.
I knew he was lying I did my own investigating and turns out he has a whole daughter he didn’t tell me about, because it was too painful!!!!!
They’ve not had contact for many years she sees him as a sperm donor wants nothing to do with him.
Aibu to not know what the hell to do now!!!
