I have namechanged as this is pretty identifying. As the title says really, I have a few siblings who I share my dad with. The mother of one I've never met got in contact with me yesterday.
For background, my mum and dad divorced when I was 3 and Dbro was 1. He met someone and when I was 4, she fell pregnant with a girl (Alpha). My dad scarpered and has never met his daughter. A few years later he remarried, had another child (Beta), divorced, met another woman, had a child note the pattern and in total has 5 children by 4 women. In short, my dad is a dick. He has a history of alcohol abuse, domestic abuse and affairs. I tolerate him but I don't like him very much.
Around 6 years ago, I was contacted by my ex-stepmum, asking if I would like to see my younger brother, Beta. After she and my dad divorced, she ran off with Beta so they couldn't be found by my dad and remarried, changing Beta's surname to his stepdads. Reestablishing contact was all OK at first, we had a relationship with him before the divorce so already knew each other but Beta has his own demons and maintaining the relationship has been difficult. He blows hot and cold for reasons I won't go into but it can be an emotional rollercoaster sometimes.
Which brings me to Alpha. To be honest, I don't even know if she is aware her mum messaged me or whether she asked her mum to do it on her behalf. Either way, I am hesitant to respond with yes, I'd like to meet her but I feel like a bitch saying no. I don't have much to do with my dad and I find the emotional turmoil with Beta enough as it is. I do want to respond, at least to let her know she has other siblings she is probably unaware of. I looked her up on Facebook and can see she lives in a village next to my town.
Sorry for the huge brain dump! I know ultimately it's my decision but if anyone has a similar story, I would love to hear how it turned out.
