Maybe a little perspective. You weren't 'dumped'. There was no relationship there to speak of. "Dumped' is such a dramatic word, don't buy into all that self depreciating pity that this word implies.
You had a date, the guy had second thoughts. You will probably have dates and feel the same.
However! - I really wish guys would learn to communicate in a straight forward manner - for example: "It was great to have met you, but I'm not sure we are a good match - good luck and take care" - bloody easy eh?
For me the bullshit really bugs me. Really bugs me. Get this:
After lots of long texts and a pretty good meeting, a couple more post date chatty texts, I text:
"You have nice eyes"
him: "thank you - so have you. Have to go - meeting a mate"
me: "Is that a brush of!!!?"
him: "no! speak later"
It was a brush off.
I think somewhere along the way men learned, or were taught, not to be honest with women.
Recently I had a long funny online chat back and forth with a guy. He then sent me a message explaining he had had 2 days with someone and they were taking it forward and it had been fun and I was funny, smart etc etc. How refreshing (and rare) to get a really straightforward message like that.
Almost as bad as the excuses and brush offs is the long patronising message after a first date. Explaining how they didn't just want to disappear bla bla bla. Like - "get over yourself mate".
Sigh.
