Is AUTHOR wrong in the post ? POST : My Ex has 3 kids, two older ones from a previous relationship, and our son. 

We had a messy break up (she cheated...tons of unresolved issues) yet she and the older two boys want to spend family time together regularly. I love the boys like they are my own. They basically are, I was their father figure for 6 years of their 8-9 years of life. My 3 year old also can’t begin to understand why daddy mommy and his brothers can’t spend every day together anymore.

Anyway she suggested that we spend time together with the boys, which was fine but the wounds are still fresh. It killed me to realize that I can’t have that sense of family every day because of her selfishness/dishonesty.

I’m feeling a litany of emotions right now and I really just want to tell her that we can’t do it anymore, but I feel like it’s selfish because it should be for the kids.

AITA?
