If I could be honest, I don't think he is very likely to change his "communication" ways, per say. At the age of 42, he'd be pretty engrained in his mannerisms.

It comes down to a question of what you're willing to put up with. And the lack of communication is obviously quite upsetting, because it's not what you want from a relationship.

You can either end it now, or give it one last shot - and if that doesn't work, walk away.

I'd be putting in some boundaries, or maybe more expectations, like no continuously being on his phone when he's meant to be visiting you. If he can't accept that, I don't think that this relationship is meant to be.

What do you two share in common?
