Is OTHER wrong in the post ? POST : Sorry for any bad formatting I'm on mobile. This is a long story so TL;DR at bottom. 

So my ex and I were together for about two years before I got pregnant and shortly after I had our daughter things went downhill and we ended up breaking up. We didn't have a court custody agreement. We had agreed I would have our daughter on the week and he would have on the weekends. And for about 3 years of her life we did that. When our daughter turned about 3 1/2 we had changed our agreement so he would have her during the week and I had her on the weekends. Because I was moving and in between jobs we felt like it would be easier. This lasted about 6 months. During those six months I would call her throughout the week and try to see her to go to the park and stuff during the week day if I could. Once I moved and got my job we went back to our old set up with me having her full time. And for a few weeks that was great but after awhile my ex would stop calling to talk to her. My daughter who was four at the time would get upset so I told him he should try talking to her more and being a little more involved and he agreed. Fast forward a year she is now five and he hasn't called in more than 2 weeks and hasn't seen her for over a month. When I let him know his daughter is upset and he should be more involved he seemed irritated and said something to the effect of I don't ever ask him if he wants to call or see her so how would he know its okay. I was shocked by this as I have never once told him he couldn't call her or see her. I told him if he wanted to be involved he would make the time and I shouldn't remind him to be a dad. 

TL;DR my ex is angry that I don't tell him to call his daughter when I have her full time.

AITA for not reaching out to my ex to tell him to call his daughter?
