Why does someone ignore/block/delete you when all you do is trying to help?

I don't know how well you do know this person but maybe if you contact someone more closer to him/her that can talk to this person. If someone would block as hard as they can to be alone, it may be ok to let him be for a few days.

This triggers me so much as well. Currently I am in a situation where my crush secretly wants someone to just save her but refuses to let others help her. But i guess I can't really help her but I can be there for her. Our definition could be different when we say "help" i don't know we are complicated. I always keep my promises. Same as him I also promised never to leave her especially when she's so vulnerable. But at certain times she wants to be alone, not necessarily blocking me but she won't really interact for few days and I really have to accept that. It's so hard to deal with this... I certainly feel your frustration in this <_<

Then perhaps he might not be the person you expected him to be. I'm sorry. I really hate when promises such as "ill be there for you" can be taken so light. But I don't really despise them as much, maybe it was too much for him to bear
