Hey, Im 19 years old and i just broke up with my boyfriend because he has alot of issues. I am curently dating another guy but my ex is always trying to be in my life for an example last night my date slept over and my ex called me at 3:30 in the morning and my date sneezed or caughed and my ex heard him and he totally freaked out on me and saying he was coming over to kick his ass and all that.What should i do and how do i get the guy i used to love out of my life for good.
