Age difference, can he like her!

I know this girl who is about 16 years old and likes a guy who is around 22. She is asking me advice if the age difference will effect the way that he thinks of her.

She is not worried about the legal side of it, but more of the chance she has with him. They talk a lot and laugh, but she is not sure if it will ever work out.

he is more of the oh I know im a nerd and dont think anyone will like me type, but is not depressed or anything. He makes jokes and laughs like any normal person, but thinks that he is not good enough.

this girl is more outgoing, and pretty but also a nerd in her personality. Doesn’t care about the looks just the personality.

If you think it will work out….. Write back!!!
And if you don’t… still do haha cause i need reasons to give.
