drama in my life just keeps comin

So drama in my life just keeps comin and I need some advise… Ok so my ex that I’ve been broken up with for a little over 2 weeks, but we would still chill and hang out and shit like that but I never said anythikng about us getting back together.. So a few days ago I decided that I was gonna cut off the strings and just move on cause a broken relationship is hard to bring back plus all the shit that I found out that he’s been doin behind my back I don’t eva wanna see or talk to him again.. I haven’t talked to him the past 3 days and all three days he’s called my house phone, sent be a social site messages, texted my mom’s cell phone, and the past two days he’s come to my work once I wasn’t there and then today I was there and he asked me to call him and I said I would but I didn’t.. I just don’t get why he won’t give up how to I get him to leave me alone I can’t deal with the drama anymore!!! I just don’t wanna be mean to him cause he has a lot of shit going on in his life …
