Anyone else have these problems

Me and my ex (child’s father) aren’t together and broke up on very very bad terms. He is not apart of our child’s life and hasn’t been around for nearly seven months (he quit coming around after he got his new girlfriend pregnant so I’m assuming it has to do with that.) Well I tend to post a lot of pictures of my son on social media (Facebook Instagram) so distant family can see him and what not, the thing is I also have a lot of friends on there that are also his friends, the problem though is I don’t even know which of these people are his friends because he knows a lot of people, all I know is someone keeps taking pictures off my page and sending them to him, this may sound terrible but if he wants to see his child then he can come over and see him, I mean it’s been six months!!! And what these people don’t realize is up until two weeks ago when he decided to say god awful things about me at a party to strangers he didn’t even know, I was actually sending him pictures of our son AND keeping him updated even though he absolutely did not deserve it. I have tried so hard to let this situation go, to move on with my life but there are always people trying to stir up drama. I’m not okay with someone taking pictures of my child off of my Facebook page, I don’t care what the reason is! And this has been going on for awhile, he tells people that I keep our son from him (even though HE’S the one who won’t have anything to do with our child) so people think they’re doing something nice by sneaking him pictures of our son since he has put it in their head that I don’t let him have anything to do with our child. Either way it’s still wrong. I don’t want to quit posting pictures of my child and it’s sad because I shouldn’t have to but I mean I can’t deal with people doing this.
