He might be the first guy to be very direct and verbal about bring unavailable.

Others might not be as direct but they weren’t available for marriage or any other mature relationship. .

Soon to be ex was stoned or otherwise drugged up often including his own wedding- that’s very much not being emotionally available , you have to be sober to be available, first example of emotional unavailability is substance abuse. Then had no place to live, no credit, no financial stability-not financially available for marriage, heck he didn’t even pay for his own wedding or honeymoon- not available or ready for marriage or serious commitment.

A guy you were engaged before had no job no income and no place to live and on drugs-that’s certainly not available for commitment and certainly not marriage etc

The point is that they are all unavailable for marriage and long term commitment. Just in a different way

This last guy was different because he was not conning you or trying to manipulate or get something out of you. He was direct about not being available. Very few people are. So I give him kudos.

But just because others weren’t direct about their unavailability it doesn’t mean they were available. You just had to dig deeper with them to see what’s up with them.
