Why would he delay returning my things when he has no feelings for me and is now in a relationship?

We "broke up" just under 3 months ago. He told me he stopped himself having feelings for me and didn't allow himself to get attached. He said he can't think on terms of a relationship and doesn't want one with me or anyone else but he cares about me, likes me and still wants me in his life. It was a situationship that lasted around 5 months, I decided to walk away.

I returned his t-shirt after 2 weeks. Im still waiting for my jacket. I left it as his friends when we all went out, his friend was meant to send it and didn't. My "ex" collected it and told me he sent it himself about 3 weeks ago before he went on holiday, I didn't receive it.

Waited until after his holiday to let him know. He said it got returned to him because the address was wrong "for some reason", but then said he forgot to put the first line of the address. How tf could you "forget" to put the most important part on a package? That was over a week ago and I'm still waiting. Found out a couple days ago that he's in a relationship, so clearly it's not that he wasn't ready, he just didn't want one with me, so didn't have strong feelings, so why delay?

Side note- he had an opportunity to tell me he was seeing someone. He was originally meant to stay at mine before flying. I offered that he can pop in for a coffee if he wants to. He said, I dont think I can now but thanks for the offer and then suggests that we play a game when he gets back which obviously didn't happen as he must have been "respecting" this new girl.

I've blocked him from everything now as it was too overwhelming for me I've cut my losses, as my healing is more important. But im just curious as to why he would delay if he didn't have any feelings for me or care about me. I understand im not a priority, more so the reason why you'd wanna get rid of it ASAP?
