Relationships

My boyfriend ignores my posts I tag him in on facebook but responds to others. It really bugs me. What should I do?

So I don't tag my boyfriend in stuff on facebook very often, it's usually occasionally because most times I can just show him something since we live together. But occasionally when I'm away or he is, I'll tag him in something I find funny or makes me think of him like a video or picture, and also when I take pictures with him or his kids I tag him. But he just ignores all of it. Yet if like this one girl, who he used to like before me, whenever she would tag him in a funny thing, he would always like AND comment on it like it was so hilarious. She's pretty much of out the picture for now due to issues she caused in the relationship in the past (I found out they were talking about maybe being together again and all this stuff). But I dunno, it seems childish I get upset that he ignores my posts, but I can't help it. Kinda makes me feel like he doesn't really care. Not sure if I should just leave it be or maybe just stop tagging him in anything.
