Found out I have half brother my mum stopped my dad from seeing

Hey guys

a few months ago I learned from a relative that I have a half brother one year older than me.

my father fathered a child in Russia when working there.

the story is allegedly my mother learned about him when she was about to give birth to me.

Allegedly the woman kept quiet she was pregnant and till the kid was one and then decided to tell my dad when my mum was about to give birth to me.

my father kept in contact by phone and visited him till I was 3/4. Think this Lady didnt know about me/my mum, not sure.

then one day she calls mother told her over the phone when she called “it was your choice to give birth. You were 38, last chance to have a kid. You wanted the kid for yourself so now raise him yourself” and hanged up.

some time later this woman called my mother had her friend say wrong phone number, this phone was sold.

my father never spoke to him after that. I guess he thought she disappeared again and wanted nothing to do with him? Idk? I am not sure if he continued paying child support.

now obviously you can’t stop a father who wants to see his kid but my father is a very weird man. He also has a relationship with my other much older half sister from previous marriage because her mother kept in contact. I really believe if my mother didn’t do this he would still be in contact with this boy.

now my mother says

it’s not her fault she found while married and pregnant he has a kid and she was very sick of this woman being annoying and calling non stop, very often, for hours when they were busy chatting about their son. Says “I was just sick of her calling constantly! We couldn’t get anything done! Maybe if she didn’t call everyday and wasn’t so annoying!!!”

I don’t know how to feel about all this. I am disturbed my mother did this. Am I right to think this was very cruel? And look at her differently now? My sister says I’m over reacting.

Where did I say I am not???

Your whole OP is about your mother. This was all your dad and his behaviour. He could have picked up the phone to his child, no?

Place the blame where it belongs.

Blame your dad not your mother

Any reason why you’ve decided to focus your anger and blame on your mother? Sounds like you’re a bit of a misogynist.

Your father was a cheater, and then abandoned his kid. That was him. Not your mum.

So your father couldn’t keep it in his pants or consider contraception, your mother stayed married to him after finding out about the affair presumably for your sake, and all you can do is be nasty about her? Why couldn’t your father pick up the phone and ring the mother of his own child?! Why are you blaming your poor mother for your father’s persistent monumental cock ups? I think she deserves a medal for putting up with someone like that tbh. Waiting for the dripfeed that he’s allergic to phones or something 🙄
