Given those cards and that flop, Pokerstove:

44 wins 57.9%
56s wins 42.1%

You were ahead. Assuming the preflop pot was non-trivial in relation to your stack size, you were right to raise and he was right to call. Your raise was right because you were most likely to win and thus getting money in there was good and might cause him to fold outright. His call was right because he only needs 1.4:1 pot odds to make it an even money call.

Like Rippy said, it will be a rough ride.

This is something that Mike Caro talks about in some articles. There are times when opponent A should raise AND opponent B should call the raise. It may sound unintuitive, but it is just a mathematically demonstrable fact.
