Anybody who initiates a divorce needs close inspection IMHO. I will never again take a 'she was so mean to me' sob story at face value. I think we'd all agree that revisionism is the hallmark of many a WAS or MLCer.
OCD - hmmm that one can be a huge problem or quite a useful trait. Combined with control freakiness or passive aggression that would be a red flag for me. If it is quietly held with no expectations of being pandered to, I don't think it is a problem at all. Quite the reverse in fact
