<human>: About three weeks ago, my boyfriend of over a year broke up with me over the phone. I will spare too many details, but I did not get much of an explanation and he was very upset/crying. We were long distance while he is at college a 4 hour drive away. He told me he would tell me the next time he was home and we would meet up to have a face-to-face chat, and he would give me my books (he has six which belong to me). 

My friend Molly also reached out to him and offered to meet up with him to get my things if he was my comfortable with that. He ignored her.

I dropped off his stuff at his parents' a week ago, and he was there. I asked him when he would bring my books, and he said the following weekend. 

Yesterday, I contacted him again (after not doing so all week) since he never came by. First, he simply told me he would bring my things to Molly the following Friday. He got angry and said he wants to move on, and talking to me makes it difficult. I expressed my disappointment and made it clear I knew we had no future together, but would like a face to face talk for closure's sake. He told me he wants "alone time" and cannot be friends with me right now; maybe not ever. I told him I would not contact him directly again.

Twice now, he has told me he will return my books and has not. If he does it a third time, what should I do? This break-up has been very hard on me, and him having things that still tie me to him makes it harder.

Summarize the given text in a few sentences.
<bot>: My ex has had multiple opportunities to return books he borrowed from me and has not, despite saying he will. How do I get them back without acting like a psycho ex?
