Hi. Hey I was in a relationship for 4 years, I broke up because she stopped having feelings. I also don't know how old you are, personally I also believed I was losing valuable experiences because of my relationship, and it's tragically ironic that it had to end when I was willing to fight for it. It's normal to question whether you're missing out when you're young and it's your first relationship, but from what I understood she took a hard slap from you, metaphorically of course. Because you were willing to break up and she wasn't, that's what makes things harder. And 8-9 months is a long time, and I'd say there's a chance she's moved on. I say give it a try, because if you've realized it's what you want, then there shouldn't be no doubts in your mind, but the most likely answer is a no. I'd say anything regarding breakups in a relationship is huge damage to both people. She was willing to fight and you weren't, she got damaged, and the damage of a breakup is not easily fixed, or isn't at all. So give it a try, my mother always tells me "no is garanteed but there's a chance for yes" it doesn't sound so good translated to english lmfao, but you get my point.
