That's one thing I am proud of my H, in that he never ignored his girls aka princesses (or son for that matter) during his icky time.
This is the one reason that I know my H is in MLC and not just a WAH. He adored his children, he couldn't do enough for them and that just disappeared the minute he met current OW. Ok so he appears to be spending a little more time with S16 now but reading between the lines I think that is only b/c of the outburst a couple of weeks ago. I get the impression from S16 that up until now he hasn't really seen a lot of his Dad even though he lives with him.
My D18 is particularly struggling with this. She was literally his golden girl. Even though she was our 'challenging child' she was always his favourite. Even I was jealous of thier closeness! Again as soon as he met current OW he dropped her like a stone and gave all that attention to OW. She has told her dad how she feels but he just puts it down to jealousy. In a very small part he is right BUT he can't (or won't) see how it has totally changed (and damaged forever) his R with D18.
D13 was 10 when he left. Two weeks later when she plucked up the courage to ask him to come home and then asked why when he said no he told her he had wanted to leave for 10 years. It doesn't take a brain surgeon to work out how that has left her feeling.
