Would you be upset if your boyfriend did this?

So my bf/baby fathers posted a picture of our daughter on his instagram. Okay great, but he put the father and daughter emoji on the caption. We aren't friends on any social media because he said he would like to keep it that way since we met. To me it just seems he wants to play single online. He not once posted a picture of me on his Instagram or Facebook which kinda upset me but it was whatever ! But to put just the father and daughter emoji? And we're supposed to be a family as he would say? I just don't get it. Should I confront him? But then he's going to know I've been snooping on his page... trust is defiantly an issue just because he's cheated multiple times even while I was pregnant. But I wanted to work it out for my daughters sake but how would you feel? It's a picture of just our baby and you can see me in the back on the bed.
