S.S.
A., What you are describing is very familiar to me. I have been divorced for 10 years and my daughter was 3 when her father and I got divorced. It is hard to deal with these emotions since we are feeling so stressed and rejected too. What I did was make a point to talk with my daughter frequently about the divorce and explain that you understand it is a change and it hurts. Reassure her that her father still loves her. Quiet time with her also helped. If she was throughing a fit in a public place, I would let her do so for a bit of time, and then remove her to the restroom for the remainder of the tantrum. It is best to let your son express his anger and pain. Then address the inappropriate behavior. Remember we too are emotional over the divorce. We feel rejected, angry and hurt. They do too. S.
