Can't beat him

[Victoryman]

New poster, excuse me if this isn't the place to post this but I don't know exactley where it fits. I just can't beat this kid in our weekly game. I've gone heads up against him and lost like 5 times now and its starting to piss me off. He's a loose player. Practically plays til every flop. Up and down most of the night but he usually ends up in the final 2 or 3. He bets real aggressivly and I can't get a read on him. I've tried fighting his aggression with more aggression but it seems he can continuously make a higher pair when I come back over the top of his bet on a pair or something like that. I've tried being rather conservative. Playing only hands where I have some kind of higher connecting cards. Not chasing a flush or a straight til 5th street. I've tried mixing it up b/w aggressive and conservative. I just can't figure out what to do. Any suggestions? I know this isn't much to go on but anything you got would be helpful. Thanks
