That's a very large age gap to bridge. There is a world of difference between a fourteen-year-old and a twenty-two year old, right down to the fact their brains work differently; the fourteen-year-old's is much less developed than the twenty-two-year-old's.

Also, as I myself am a month shy of turning twenty-two, I really have to question why someone that age would rather be with someone who is barely a teenager than an adult closer to or over his own age. It is INCREDIBLY unlikely that all intentions behind that are honest, and they are certainly not appropriate.

In my book this is both legally and morally reprehensible. However, I'm not in the relationship in question; that's something up to the parties involved (assuming the law doesn't get involved for them). But I would suggest examining all the problems and consequences of being in such a relationship at this age before proceeding further.
