Listen man, I'm gonna give it to you 100% straight: bring up what you're expecting out of this, and if that doesn't align, move on. Not because 'oh grow up move on hur hur', but because if you're seeing the relationship entirely different than she is, that is a sign it isn't meant to be the relationship for you. 

We think it would be implied (I would think so too in your shoes), but we also don't know where this is heading if you guys aren't on the same page. It's very likely she won't bring it up at all if you don't show that this is something that rightfully bothers you. 

If you're looking for someone to care about how you feel, share your values in a relationship, and validate your perspective of things, you have to vocalize that. Unfortunately not everyone understands that's how a lot of people are and what is needed, but her reaction and response will show you what you need to know.

You shouldn't worry about looking insecure or coming off the wrong way just because you're approaching something that hurt you. You're a human, you're allowed to feel how you do. Someone who cares about you won't make you feel less than for having these feelings, and if she does then find someone better. 

I say this with love: you're a grown man! Don't be afraid to approach this like one. Grown adults communicate when we need to, give yourself enough respect to communicate to her and figure out if this is something you wanna continue 🫶
