When you play against such an aggressive player, you need to wait for a good card and only through this you will be able to win it. It is very difficult to understand how such players play. Once he can bluff and you can make a pass, and the second time he can have a nuts and you can call and lose the whole stack. I can advise you to be patient, and wait for a good card and do not pay attention to the fact that he constantly raises. Set a goal to wait for the nuts and win as many chips from this opponent.
In your situation, I think that your opponent just wants to win the pot, and most likely his card is weaker than yours. But what this is to understand, you need to call, only so you will understand right you are not. I have such an opponent in offline poker. When I play against him, I get patience, and when I get a good card, I win to the maximum.
