I like to cheat sometimes, but never online. Did he tell you to use the trainer online? did he use the trainer online? perhaps it's just for personal, SP use. Don't be too quick to judge.
Either way, cheating online is a way of life... it sucks, I know, but there's not much any of us can do other than tracking them down and banning them, and the law is always one step behind the cheaters.
I don't think you should give up on online play yet. Just get used to it and help counter cheating by reporting it to your server admin.
