Thank you for your question.
The past is the past and some people either chose to tell your their past because they feel they should be honest with the person they are with. This builds trust and is a good start because the girl was open and honest about her past.
She wanted you to know and I am sure she was worried about how you would react specially if she knows how you feel about intimacy.
You should not even be thinking about wether your good in bed or not because when you love someone that is all that matters, it is different when you love someone. It is not about performance it is about being close to the one you truly love.
Unfortunately I didn't clarify which i should have, She didn't tell me, she hasn't told me much about her past relationships, it was actually the family member, who was intimate with her in the past bragging about it.
Ok, that was wrong on the family members part about bragging. But you do have strong beliefs and it will be hard for you to see past her past.
The reason is because this might be what you think about and not focus on the relationship.
Is it stupid for something like that to bother me?
No, not at all.
It is very normal.
I've already broken out of my shell in so many ways, with this person, told her things i've never told anybody, felt things i've never felt, I know there is no such thing as being perfect for each other
I jsut never imagined that the thing that could be wrong, would be so big
Should i talk to her about it, that i know about her and my family members past?
It sounds like you are very comfortable with her and that is good. Yes, I would talk with her and mention that a family member mentioned you.
You want to make sure that the family member is telling you the correct story.
That's true, i didn't eevn think of that
Well thank you so much for your advice, I really needed it.
