Mimi, I just asked you the same stuff on MrsH thread!! Funny. H and I separated in 12/06...week before xmas. He was EA with OW until about mid-January. He said it started about a month before he left. As far as MLC...I don't think he has been quite right for a couple of years...nothing overt...just different.... He did go off the deep end! Ignored the kids, gave me no financial support and filed for D fast! I think when he moves back in it has to be all or nothing. My D5 has had a terrible time and I think him spending a night here and there or weekends will confuse her. I do think the trigger point of the MLC was when my D1 was born in 2/06. My H turned 40 in 5/06...she is his 4th child. He has two sons from his first marriage. I have been very close to the boys all along. I helped raise them. The whole situation is so fragile right now! How did your kids handle the transitions?
