Hi Pups - thanks for the reply. It was necessary to find out what was going on and I was baffled as I could not find any explanation to her yoyo behaviour. At one point I seriously thought that she had developed some form of impairement or MLC. I do not want to get back with her, but I do care about her and I do not want her to be taken advantage of by OM. Whatever happens to her will impact on our children. We are both professionals in the same field, I earn slightly more, but she is from a wealthy family and is not interested in money / pension from me. Proceeds from the house will be split 50/50. the children will spend equal number of days per week with each one of us. Finance and assets are not a contentious issue here. No maintenance to be paid by either of us.
