What do you think of this guys?? Really need your advice?

Im apart from boyfriend of 9years for study reasons %26amp; about to finish. He is so angry with me says I left him but he wanted me to finish uni. It has been hard apart. He now wants to break up altho i have waited for him ... so I say painfully say okay I will let him go but need him to return my things. He says he wont return my things then says some angry stuff then he asks for sexy photos of me etc ... When I agree to let him go he suddenly turns around asks for sexy stuff of me. He never trusts me - I am one of the most loyal people you could meet. He has no reason to not trust me. How can I reassure him cos he is being so angry %26amp; unreasonable .. I think he might bed epressed cos he's struggled with this in the past. .... I am confused - I am in another country. Dont know what to do. I say he if he wants me to move on he needs to return my things but he wont. Why? I have a few of his things %26amp; have offered to return them. I dont want this to get nasty - it hurts too much.What do you think of this guys?? Really need your advice?
I would not trust him with sexy photos of yourself especially since you two are breaking up. If you were wise you would stop playing his games and cut off communication with him. If he wont return your stuff call the police station or a lawyer and ask if there is anything they can do to help. But like I said the best thing is to cut communication off with him.
