He still won’t get rid of it-update

My boyfriend and I have been together for ten months now , we are moving in together in the next month or two . But still he has bags and bags ( I mean huge trash bags filled with clothes and jewelry from his ex ) that she never came to take . And he won’t get rid of it I’ve asked countless times of him to text here to pick it up or give it away to charity but he won’t . He says what I’m supposed to just throw it away ?! I know she asked to come pick it up two months ago and in the beginning he said yes then when she asked again he ignored here . What should I do ? What can I make of this ?

Update

I tried to talk to him but he used the I’m at work line . We are now staying at his dads house sitting for a month . The stuff are there I cheeked . So I’m gonna have a chat with him tonight .
