LT—I think susannah is on to something when she says he sounds like he was getting fed up with constantly having to prove he cared. I’ve been there with 2ex (not comparing you two otherwise, nothing alike). It is hell on the person having to prove they care. I doubt it’s as hellish for a therapist who’s less personally involved, but still frustrating.

And I am wondering if that dynamic exists in your personal relationships: people feeling they have to prove they care. Tbh, it does sound like it from a few relationships you’ve described on here. Not because you are doomed to be difficult or a bad person or whatever, but just because of the way you present yourself to them. If that’s right, I think it’s a dynamic you might want to work on changing with the next therapist.

As for blame or fault, this is a situation where it’s maybe better to consider responsibility and try to identify your own, so you can learn from it.
