Hi Christin

Whilst it doesn’t sound like you were compatible romantically, it sounds like things were left on good terms. I think it might depend on the individual regarding appreciating contact. That being said, I think it’s a very kind idea. I know I would be happy to communicate as friends in that circumstance.

I think if you sent a message you’d very quickly find out if this individual would appreciate contact. Seems to me there’s nothing to lose. But perhaps it would be important to communicate boundaries if you are not interested in continuing dating? As people can be easily confused.
