I really don't think you should take any of this personally and as blunt as it sound it is in your best interest to just move and not ruminate over as to why you were ghosted, you'll just make yourself sick getting into that type of pattern. Unfortunately, this type of behavior is very common with young people today, though it's far more often seen with young women, but that doesn't at all excuse it. I'm not going to lie to you though, if someone ghosted on me after we had spent a good amount of time together I'd be furious to say the least, as I'd feel that this person feigned any form of interest and used me for some sort of benefit (boredom, attention/validation, etc.). Sure, if someone did this to me after a first date or something it'd be annoying and make me mad but what you are discussing here takes it to a different level.
Try to look at this as a learning experience and not let it hold you back from meeting other potential romantic interests. You essentially just weeded out a fake person who cannot communicate at all, due to a variety of personal issues that individual has.
Good luck
