Is it worth it?

My ex and I broke up three months ago and we still have each other's things. I texted him a couple of times asking when I could meet him to get my things and every time we would start making plans, he ignored me half way through the conversation. I haven't talked to him in almost 2 months and I'm just not sure if it's worth the emotional stress and pain to try and get my things back. When we first broke up I had really bad anxiety and I'm just scared that it'll all come back.
