This guy sounds strange and flaky indeed. He is lying to you and nearly caused you harm, says that he is a Medium and so forth. I surely would advise you not to waste your virginity and time on him. I would say move along because there are lots better.
DON'T waste your youth and time on such nonsense.
Sounds very strange. You can live without this guy right? Then run run run
Can you explain what he lied about that caused you harm? That's concerning that he did that to you. And now he is making up this nonsense about being a medium. This is what's called a pattern. When someone lies repeatedly about things, it becomes a pattern and it means that this is what they will continue doing. If you were smart you'd thank him for his time and break it off because boys who lie all the time like this are bad news. Especially if his lies cause you to get hurt somehow. You need to think about this logically. He sounds like a bad choice and it's time for you to throw this one back in the river.
Hi. Well, my advice to somewhere your age is pretty consistent. Boyfriends are a huge distraction from the important things in life at your age. School, job training, college, experiencing fun things with friends, exploring who you are and developing a strong sense of self are really what needs to be the focal point right now. Boyfriends get in the way. And especially ones who out of the blue claim to be something that your gut instinct tells you is phewy.
I too would completely ignore this new 'information' about him. But if it doesn't sit well with you, move on.
Regardless though, make sure your boyfriend isn't the center of your life at your age. good luck
Maybe mediums exist, though it has never been scientifically proven. Maybe they don't, in which case he still might not be lying, he might be delusional (in other words, telling you something he believes to be true whether or not it is). It seems like an odd thing to knowingly lie about (unless you are saying he is simply a pathological liar).
My suggestion is if you like him, live with the "medium" thing, treating it as you would any other quirky belief he might have, until you have any proof one way or the other (i.e., that he's piped in to the other world or that he is crazy or pathological.) But if you are creeped out or don't like him or don't trust him, say goodbye.
