Bowyn Aerrow,
I don't know you or Blue, so this isn't really any of my business, but something about reading this thread and what happened to you is just really bothering me. I am so sorry that this happened to you.
Blue sounds passive aggressive, which is a form of abuse, and no matter what happened between you guys (from big things to really small things) nothing could justify what has happened to you. This kind of running off and disappearing is not just a sign of emotional immaturity, but is also a sign of serious malice.
I have no respect for someone who cannot at least come out and say to a person - for whatever reason (x,y,z,) I'm not interested in you anymore. I have a friend, who I recently met, that is an MD/PhD in psychology, and I discussed your situation with him, to see if he could offer me any advice that I might be able to relay to you, and he basically said that even if you aren't thinking of these things right now, this all might have a huge impact on your ability to trust people, and how you might behave in future relationships too.
I don't know you so - please don't think I'm saying anything from a position of authority, but I think you should read up on things like:
- the passive aggressive male
- narcissistic personality disorder
- histrionic disorder (which often has aspects of narcissism and passive aggressive personality issues mixed in there).
This might help you understand what happened (only you can say if anything you read pertains to Blue as you knew him).
If you can, focus on yourself, and get the answers from other sources that you can't seem to get from Blue, because trauma like this, since it is emotional in nature, might come back to haunt you later if you aren't able to spend some time processing it, and not getting answers from Blue about why he did this is just so cruel that I don't know what to even say.
Best of luck, and I hope things improve for you. I really do. Hang in there and spend time worrying about YOU, it sounds like Blue is worried only about him, and if he has a problem - well - at this rate he needs professional help because returning an email, a text, or a phone call is not that difficult.
It's malicious what he is doing.
That's my opinion, and I'm sorry for you.
