There’s just too many negative triggers for this family: he comes home with her car, they won’t answer the desperate texts from her family. They acted in a completely inappropriate manner. That’s my opinion......may be wrong, but with what we’ve been given I can only see them as some very shady people.
It’s nobody’s job to ‘give’ you anything in this case. You aren’t involved.
Wait and see how it all falls out; then register your judgement.
