<human>: Can you give me a shortened version of the text?

My ex (27f) broke up with me (32m) a few months ago after a 15 month relationship. It was definitely a seriously relationship. Not only that, it was really my first serious relationship. She was the first girl I fell in love with and had any strong reciprocated feelings for.

It's been a pretty rough time since then. I started feeling like I was rounding a corner but then found out that she got a job where she is going to stay in the same town as me (she's European and I had been expecting on her leaving the country soon, which I think would have helped). Anyway, the news of her getting a job she's excited about has made me sort of relapse and I'm feeling pretty awful again.

I am just curious to see if anybody else has had a similar experience of getting into their first relationship this late, and having to deal with the heartbreak of it ending. I know breakups are never easy, but I feel like on top of the sadness I'm dealing with stuff I should have learned to deal with a decade ago. So any advice or shared stories, or whatever, would be appreciated.
<bot>: Can anyone who didn't have their heart broken (or a real relationship) until their 30s tell me how they dealt with it?
