As we do not know all the details it's impossible to know what is best. It does seem a long time to hold a grudge though, but sometimes there can be pain that is not possible to overcome.... Maybe your previous husband's recalcitrance is a clue as to why you are no longer married to him.... Whatever the reason, maybe it's best just to accept the things we cannot change and find a way round it.

Nezumi65. I am sad to hear that your son is disabled, but I think you and your husband are the good example of the best common sense way to deal with things. It was kind of you to write and tell us and demonstrate that people do manage to keep going when life gives them a situation which means finding ways of coping with something more demanding, and just take in their stride what might seem difficult to others.
