You’ll be fine OP! More than fine! I went through this exact same thing summer 2016, though I was 28. We split as I wanted kids, now, and he ‘might, someday, but don’t know when’. It came out over a few months he wanted to basically say ‘maybe someday’ and I wanted to start a family soon so we split. He did the dumping which hurt at the time but I’m enormously grateful for now as I know I’d have been miserable with him and dumped him a while later. No man is worth giving up having a family for.
I met someone amazing a few weeks (!) later, was straight on the second or third date about why my last relationship ended and that I wanted kids within the next few years or so. Didn’t put him off as he felt the same. We’ve been together coming up on two years, hoping to TTC next year. He talks about kids and babies all the time and is the first to want to hold a baby at a party, talks to random kids who run up to us at the park, brings up how we would like to parent in the future and has started a couple of savings accounts for a house and for a child, encouraging me to do the same. It’s lovely being with someone who wants the same things and I now realise whatever happens with my OH or my family plans, I’m so so much happier having broke free and having the chance of a family than I could have ever been wasting away the months and years with my ex while I felt like I was being held back and having a ‘maybe’ carrot dangled in front of me.
Stay split, fresh start. Are you gonna move? I moved into an amazing house share with an en suite in a busy fun part of a new city, housemates ranged from 21-40, perfect mix of socialising and new friends and solitude. Started a new course which has massively increased my prospects and earning power. Had an absolute blast dating and getting used to being single before committing to OH after a few months of knowing one another, moved in around a year in. Happily living together and planning for our future.
From what I can gather ex met someone quickly too who is younger and more fancy free and not in the stage of life I was at, suits him and he seems happy. We had a good few years but it wasn’t meant to be, I’m not fucking around with something precious and time limited as my fertility nor should he have had a baby he didn’t want.
Trust me OP, it hurts but it’ll pass and whatever happens you’ll look back as this being one of the best things that ever happened to you.
