<human>: Give me a shortened version of the text

So heres a little summary of things so far. Last year, I [19] started University and met a girl [19] that I quickly starting to develop feelings for. Around January I decided to ask her out on a few dates. We went on 3 before she decided she didn't want to progress. I hadn't spoken to her since then and haven't found anybody else of interest. 

Two months ago I started online dating, but after sending a message to nearly all my potential "matches" I have yet to get a reply from a single one of them. I figured I would stop trying online dating as it clearly wasn't working out for me.

Fast forward to present day, I've starting thinking about the girl I met last year again. Last night I had a dream going back to when we met, and those dates, although the outcome was different. We ended up getting married, children, and had a comfortable life together. It was probably one of the best dreams I've ever had.

When I woke up, I initially felt a little lonely and sad that it didn't come true. But as the day continued, I started to ponder the though of giving this girl another attempt. 

Is this wandering into one of the "never do this" rules of dating? Or would you guys give the green light?
<bot>: Met a girl last year that didn't work out. Tried online dating, didnt work. Considering contacting this girl again after a bit more than half a year. Is this a good idea or am I just stupid?
