I have a narcissistic ex who still obsessed over me and stalks me on all social media even though I block him he continues to make fake accounts?

And watch my pages. He has a new girlfriend and will message me he’s so happy and how she’s a women she barely just turned 20 lol is he really as happy as he seems lol he’ll message me little things like he could make me fall in love again or he seen I went on a vacation and sent me a text saying use protection. He watches me every single day multiple times behind fake accounts
