omg single mother of three part deux

the kids love him and the oldest especially when asked wants to live with his daddy. i plan fun things [example christmas sugar cookie party, movie nights, tie dye tshirts] he rarely gets involved and he loves them but i think is unaware of how hes acting he considers being on the same acre of land spending time together. he in turn loves me and our daughter very much and our little family does fun things and interacts very well even if its just sharing our day at the dinner table. i know he loves them and they love him but i wonder now that circimstances have changed if maybe he is so "unresponsive" for lack of a better word,is because the first marriage was so miserable and he didnt bond with them hardly at all in their first years of life? now that he has custody and his mother is raising them she must call him for approval on everything from field trips to when they can see their mother. he isnt having to drive them or look after them so it seems his mother should have that desicion to herself right? idk i have no one to talk to on this matter and its nice to get some feedback and straighten it out in myown mind
