What were his motives for catfishing? Were you giving him gifts of value? Would your reason to expose him to other games to give them a heads up for not getting ripped off? Could he find you and hurt you physically?

It sounds like you feel bad about getting tricked, but whatever he took you for (games?) is something you are ok with losing.

Just consider it part of the online game fantasy.

There was a poster on here around a year ago, also from UK, talking about an online relationship with a person who sounds a lot like this one. Could it possibly be the same catfish?
