Hope you're feeling a bit better today OP!
The idea of meeting (even just phoning) for "closure" sounds awful to me. Who wants that awkwardness?! Either person.
I dumped someone (OLD) by text after 2 months.
Bottom line - just no spark.
I said that (using an in joke we had) and acknowledged that he might find a text quite abrupt - but that I personally would rather receive a text than meet in person, so thought he might too. And that if he wanted to talk, that was fine (whilst hoping he wouldn't!)
He replied that he also had spent the last date "not feeling it". Which I don't think was the case at all, but texting allowed him to retain some pride.
What could I have said if we'd met? Would it have been closure to know he was the worst kisser I'd ever met, a hypochondriac, and worst of all left all organisation of dates to me?
Kind, if blunt, texts are fine.
My last boyfriend dumped me by text after 15 months! I actually called him to check that he had, in case it was a joke! We ended up having a nice chit chat about other things. End of the day - what's there to say when a relationship ends? Sometimes, the spark just isn't there.
He may have been "love bombing" - but more likely he was just throwing himself into th fun of dating someone new, until he realised it didn't have legs.
Don't let it put you off - sometimes it'll be you that is backing off!
It's hard to say how not to invest too early. But I would say this - take everything said with a massive pinch of salt.
