Get over the love I just lost

I’ve recently been talking/dating a really sweet down to Earth guy. He is the lead guitar player in the band that I sing in. Our moms don’t really agree but not over me and the guy, over other things. But, all of a sudden the guy just decides to quit talking to me and dosent even tell me ;instead he choses to ignore me. Just out of no where. Because everything was going perfect nothing in that relationship could have been better. I dont understand how a guy could do so much for you in so little time, then leave with no reason, with no explination , and without a word. But still, I think he is THE PERFECT GUY.
