How do I answer to questions about my dad and childhood

Hi everyone,

I’m 25 and I would like some advice on how to deal with the questions that often happen more in dating situations.

When the guy I’m with starts to ask “why do you never talk about your father?” or, “you never go at your father’s” or just “what about your father?”.

I’m asking just for a guy who I don’t know enough to speak about it, because of course when I’ll be in love and secure I’ll explain, but my father was a narcissist who deeply affected me with the way he educated me, considered me as his thing and we were way too fusional, then he abandoned me and told me it was my fault at the age of 12, and he never explained me what he meant.

And of course I’m under therapy and working my best to heal and to stop letting this childhood affect my love life, or global life, and I don’t want to speak about it too early to not be seen as the “daddy issues girl”. I want to be seen for who I am, but I don’t want to lie, don’t want to seem rude or mysterious, I just never know how to answer and it makes me insecure when the person in front of me starts understanding that there’s a dark thing.

Maybe someone has the same issue with another topic?

Thanks for the advices or ideas.
