So my ex and I have two beautiful little princesses together. Ones 3 and the other is 1. We split up over a year ago. My now fiancé and I have been together for almost a year now. My 3 year old loves the man I’m with now and they have such good moments doing things together, cuddling at night time, playing games, etc. well they argue a lot too and by argue I mean she acts like she absolutely hates him and pushes him away, tells him she hates him, hits and if she’s really whiney and tired then she’ll cry. Question is what can I do? Have any of you ever been through this before? What did you do?
