The problem with age gaps, especially ones as large as this, is that both people will be in two very different points in their lives. This can lead to them wanting different things, and it can cause disagreements because they won't see everything eye to eye.
I know this from experience because a few months ago I was dating a 20 year old. It ended up not working out because he wanted to get married as soon as I was 18, but I didn't. He was more serious about the relationship than I was, as I'm only 16.
This could be the case between the 14 and 22 year old, only its an even bigger age gap which can cause more varying.

While it is possible that it could work out, I think it would be best if the 14 year old waited until they are of age before getting into an 8 year age gap relationship.
