Ex bf

I broke up with my ex two weeks ago. It’s what was best for me. He was disrespectful to me throughout the relationship and I gave him too many chances but he just never changed. We have broken up multiple times but never more than 2 days. But in the end I decided I wasn’t happy in the relationship anymore and broke it off. He has been texting and calling nonstop, showing up at my house unannounced. Contacting my family and friends and he just won’t accept the breakup. I have him blocked on everything and he just won’t let it be. I don’t know what to do at this point. I don’t want to hurt him and be rude but also he isn’t respecting my wishes.
