Advice? Opinions?

So long story short my brother in law doesn’t come around my sons. He hasn’t seen my almost 3 year old for 2 years and hasn’t even met my 2 month old. He’s been really nasty to me since the beginning. Talking to my husband, telling him how weird I was (social anxiety problems 🤦🏼‍♀️) that no one likes me, I’m stupid, etc. Every time I would be protective over my 2 year old (baby at the time) he’d message my husband calling me crazy. I was “crazy” because I didn’t want anyone all up in his face when he was a newborn. “Crazy” because I didn’t let his mom baby wear my baby. “Crazy” because I didn’t allow his mom to give me (10 month old at the time) chips. “Crazy” because I told his mom “no”. Dude is just pathetic. All he ever did was talk down to me and belittled me. And when I two miscarriages (before my other son) he said, “well, you probably would’ve loved it more than your son.” “You should’ve worn a condom” What in the world is that supposed to mean? I love my son.... and if I show compassion towards my future babies, so what? Like I don’t understand... fast forward to a couples days ago, he sent my husband a video, saying, “I can see this be you and your son lmao” basically making fun of my husband and son for being short.... opinions on that? 1.) he’s a two year old 2.) he never sees him 3.) that’s just too mean (my husband is 5” and my son is in the 40 percentile for height. But that’s none of his business? He lost all privileges... and even if he had privileges, my sons height isn’t nothing to laugh about. Tell me I’m not crazy 😢😣
