HC I have no idea what you're trying to say, can you elaborate a little?
Do you mean, for example, say he left a favourite plant with you and asked you to watch it, which you did..........but he's not ignoring you and being rude when you contact him?
It's hard to tell without knowing more about the actual situation.
"while ignoring u and being really rude anytime I attempt to make contact—"
Because he doesn't want to talk to you anylonger, but, you keep making contact anyway?
It appears to me that any person who doesn't want to have communication with another, and this other attempts to make contact anyway ... eventually, a person either ignores, or becomes rude to get the message across ...... to leave them alone.
Logic would dictate that this man doesn't want you contacting him .. so don't.
If you are his friend, then keep safe as promised without any expectations on his part to furnish anything more, and this would go for any friend.
You started this off by saying when you attempt to contact him, he is rude to you ... so, the implication is in place that you continue to contact him.
And the reason why he does it, isn't in your need to know .. for you were a need to know, then he wouldn't be ignoring you.
If you promised to safe-keep something for somebody, then doso ... this is what a friend is, HappyCrab.
However, it doesn't seem normal for a Pisces to have such an attachment to anything really, except our children or art.
We can look here on a daily basis to see that Pisceans, especially the males, don't attach themselves to people like that. In fact, we see the opposite .... we disconnect, rather than connect .. if our attitude is indifference, or we present "uncaring".
So, I wouldn't be quick to assess that the purpose of leaving this item with you is for keeping a foot in the door. We really don't even observe the need to have a door cracked open .... and I would think that if this were the case (a foot in door), then he would be charming, while pushing away at the same time.
A person who has intentions of manipulating another like that isn't going to be rude to you ... he's going to be Prince Charming to you, to keep you snared. To show rudeness, or ignorance isn't indictative of a person looking to keep you in a web.
I would think his only reason for you keeping his belongings is because he thinks he can trust you as a friend ... and has is just carrying on with his life.
It's not that the wind is blowing ... it's what is in the wind.
Wind blowing ... you believe it's a prize possession.
In the wind ... if it were a prize, he'd have possession of it, not you.
