I don’t see any evidence for testing his previous partners badly
His first wife was a short marriage where they both agreed they were unsuited from the beginning
It was a uni relationship and they married at 23, no children and divorced after a few years when he met Marina.
His second marriage has lasted a good 27 years, they are amicable, there’s no reason too say he treated her badly.
She wasn’t distraught that he met another woman.
If I was either of his exes I would hate to have the level of pity some people are giving out
