Hopefully, theland, they will sort it out again soon for themselves. I think that's a good idea from Alba about writing to them both, but be careful not to take sides- assume they will show each other the letters. You can only tell them it upsets you and your wife, really and ask them to do their best to sort it out. But it really is up to them, and sad though it is, they may just not get on. Don't get into a position where you end up only in contact with one of them though, they need to work it out themselves, if they are going to.
