This is called retroactive jealousy, i used to have this but it’s gotten a lot better. I’m also a similar age to you so i understand how this feels. You honestly just have to accept that she loves you and she’s not with that person for a reason. Yes, they have a past but you two have a future together. Life is too short to dwell on things that happened, focus on the love you have for her and building memories together! :)

It doesn’t matter at all. U might not be the first but ur a completely different person and ur going to experience things together that no one else has bc of that. Don’t get hung up on someone’s past it only ruins a relationship and it doesn’t actually effect the relationship it was something that already happened

you're still her first in many ways and will continue to be. if she's anything like me, as the days past, she'll remember less and less of him, and one day, will struggle to remember his name.

Same, but somehow I feel worse when I think about the previous hookup my gf has had and not about her ex bf as much😭
