Crazy ass ex

Ummm 1 year and 6 months worth of bullshit. Nagging, fighting and just not getting along. It ended! New years, I found some one else. Someone who respects me. Someone who cares! My ex has been calling, texting and it had been annoying me. My boyfriend doesn't like it. We joke about it. But it upsets us. It doesn't affect anything. What do I do? I can't take it anymore *pulls or hair*
