I think we get along much better now that we're not together.
I don't ask what she does with the money she already gets (it's none of my business, and I know that kids are expensive)
she and her fiance own a house now, and the family seems to be happy all the time - having my kid in a positive environment means a lot to me
her fiance (and his sister, his dad, and step mom) like me.
sometimes I take their baby (she's actually almost 5 now) along with my kid, and the little one is also always happy and in a good mood
I don't think my ex is being difficult, I think she's being realistic, but setting a high goal so that compromise will work in her favor
