TL;DR - Do you get a nervous energy or achy pit in your stomach after a block and delete?

Backstory: LVM 1- been seeing an old school friend since February. A few weeks ago was his last sleepover and I woke up feeling like something was wrong from the night before. I asked about it and was told everything was fine. So I let it go. The next two weeks turn into me initiating all contact. Last conversation was a FaceTime he answered and we spoke about 3minutes ending with him saying he would call back. He hasn't to date and It's Freaking Mother's Day! I blocked him and deleted from FB. NVM2- ex/ babydaddy decided to be a total ass today kicking our grown (23) son out and taking gifts to our son away from him. All while yelling at us both. My son was living with him, working for his business (unpaid), cleaning house and babysitting his other kids for him for the last few years. My son has Nothing to show for it. Not the car he was promised or the education plan we had when he initially moved there. But somehow this scrote had the audacity to yell at us when either of us said a Single word to him. His act was so ridiculous that neighbors came up to us as we left saying how we didn't deserve that and he's just mad his free labor is gone. I told my son to block him after he showed me a text rant that he got soon after we got home. I have blocked him as well.

Both these cases I know that I am doing what's best for me and my kids. I cannot however, not shake the feeling that my blocks will do more harm than good. Any advice ladies?
