Ditto in it. My h has never been interested in other people as people. He has one friend outside his work and very rarely sees him. If I ask how his sick wife is, my h can't answer me because he hasn't asked.
My h did things for others purely as a means of getting what he needed himself. Eg people thinking he was the good guy, when actually it was all about him and he ultimately resented what he was giving. This also includes his own family.
My h covered up his disinterest as not prying in others business. Rubbish, he genuinely was not interested. He didn't want others to know who he was so he projected this on to other people as a means of maintaining distance. That includes me btw.
I guess it's now at midlife that my h has realised how few people/ friends he actually has, hence my uber clinger. Outside of this house he has pretty much no one.
Relax - they have a Karma bus ticket to ride.
