How do you feel about me learning more and more about my significant other and her past every day?
Is learning about her past bringing you loser together?
I'm not sure, If anything it feels like it's becoming more risky to be with her.
Well, even if you think it's becoming more risky, learning about her past is a good thing. It'll both help you become closer and show you potential red flags. I hope everything works out for you in the end.
I just want some way to be happy.
You shouldn't hold it against your partner for learning about her past, as that is considered a good thing. You should share and learn about your loved ones as much as possible-- and hopefully you learn to be happy with them in the process.
