I have been separated for three years, divorced for 1.5years, I met a man that has been separated for 1.5years divorced for six months. We have been dating for a year now... We both have children... Mine are 3 and 5 and his are 4 and 8. Every time we have a weekend where we just have 2 out of the 4 children, things seem to be fine. Every time we have all 4 children I find that by the end of the weekend I am the one that is so frustrated with the kids and him. Why is this? My children are here all the time and he gets his two children every other weekend so when his kids are here I feel that my children are to blame for messes, broken toys, missing toys etc. What can I do? I am starting to feel that having all these kids are putting a toll on our relationship and I feel that all I am doing is making his life miserable, but am I the one to blame?

Its so hard to smoothly blend families, and it can be frustrating, and overwhelming.

Just curious why you blame your kids, and why he frustrates you? Seems to me you would share the load among all the kids, and work together on this. Is that not the case?
