Is it bad that I get resentful about my girlfriend's sexual history?

Anonymous

So I started dating this girl couple months ago. It's been going very well and things are getting rather serious - she seems to be very into me and has been bringing me to her parents a lot. We both knew we were not virgins when we started dating but didn't know much about each other's sexual history. Recently we were chatting one day and talked about this topic. She's admitted that she's still friends with her ex, but she wants me to trust her, so she gives me her phone password and allows me to check her phone whenever I want to. I did check her phone and while I do trust that she would not cheat on me, I went through her texts with her past hookups/fwbs and I can't stop thinking about her sexual history. She's had a lot of sexual partners in the year prior to dating me, about 8. She's said that she has a very liberal mindset when it comes to casual sex, but she is serious about us and is able to commit to a real relationship. I also get secretly resentful, because she's given so much of herself to so many other guys for literally nothing (she would even offer to go dutch on hotels!) and I'd done so much for her to get basically the same things. Some of the messages were really really slutty, which also makes me feel like she doesn't crave me sexually as much as some of the other guys she's hooked up with, which tbf, she's always been honest that she's wasn't attracted to my looks initially (she's a tall girl and I'm a tad shorter than her). So yeah, what do you think? Should I let the past be the past and treat this as a new relationship? Or are my feelings justified?
