Meeting my half sister for the first time

I have to say I am a man and I am aware this is a woman's forum, but the subject is pretty complicated so here goes.
My dad raped some women in Poland in his youth and then ran back to Romania when I was born to my mother, who was in a consensual relationship with her.

So a few months ago I got in contact with what would be my half sister from a woman he raped and we decided to meet. We didn't run a DNA test or anything, but based on what my father and her mother said, we are quite sure we are related.

Next week we will meet, we are both 32 years old (she is a month older) and we will meet in Romania since she will come visit here. I am romanian and she is polish as I said.

My question would be, what do I say? While we did talk about alot of stuff online, somehow it feels much more serious now that we meet in person.

I know she said that what my dad did to her mom was horrible, but I was thinking that without that she wouldn't exist.

Should I bring it up, either that or my dad situation, but she will probably wanna talk about it.
Maybe just focus on what we've been doing?

I'm way more nervous than I should be, but I want to make a good impression.
Got any advice for me?

 

Not with any personal experience, I have watched UK TV programmes such as long-lost relatives and the one about 'foundlings', where kids were left on a doorway or church by the (usually) very young mother and then later in life, much later, these programme researchers found them and connected them to their real family. Moving stuff.

So; my suggestion is:

1. to bring someone (close friend) with both of you, to meet as two pairs. The friends can walk away and leave you alone but be on hand if the situation may become embarrassing or worse.
2. focus on yourselves, your own lives, you own futures. What your parent(s) did is in the past and cannot be changed but you two can create a whole new world for yourselves without dwelling on that baggage.
3. I've not heard before, someone stating the positive to come from such a terrible event. I think it's true though.
The child and siblings are all innocent.
If your 1/2 sibling wants to ask questions, be prepared to answer them - truthfully. If you don't know the answer be honest and say so, adding that you'll try to find out, if you can/will be able to.
4. She will likely ask if she NEEDS to know and you may be the only one she can accept the answer from. If she doesn't get it, she may feel the meeting is worthless and vanish.
5. Don't dive in to heavy chat from the beginning, let her dictate the pace of the conversation and you be the strong one.
After all, you were born to a husband and wife, your parents. She was born to a mother and has never known her father and I expect she will be very nervous.
You both will.
But give her space to feel at ease with you; to feel more at ease with the situation.

My 2c. (BTW, I'm a guy but I suggest you'll need input from both genders if you are to make a success of it ).

 

Spread love, embrace the connection, let go of the past. Be present, be peaceful, be open-hearted, give here space.

Trust the journey, man. Peace and love to you both. ✌️❤️
