<human>: Could you distill the essence of the text into 1-3 sentences?

My ex and I have been broken up for a month. He dumped me by saying he doesn't love me anymore. We tried to work on it for 3 weeks but then he said he feels the same way. I gave everything to that relationship and I was a great girlfriend so when he said he didn't love me I knew I gave it my best and I am able to move on knowing that. Anyway, I stopped communication with him immediately. I have no desire to reconcile with him considering this is the 2nd time he's done this to me. I am happy and the last thing I want to do is to speak with him to set back my progress in moving on. I sent him back his things immediately but he has still not sent mine. He knows my address because prior to breaking up I sent him an email with it. I don't want to speak with him and we live in different cities. He has tried contacting me but I have never responded. I am not sure what the best way to get my things back is. Should I ask his sister, ask my best friend who lives in the same city as him, have my Mom call? I would rather not get anyone involved but at the same time I prefer to avoid having to contact him ever again.
<bot>: Cut off communication w/ ex when he dumped me but he still hasn't sent back my stuff even though I sent his.
