A relationship can survive adultery, but only under certain circumstances. Having an affair - just one, mind you - can be a big roadblock, but you may be able to go around it if you first answer these two questions:
<ul type="square">[*]Do you feel as if you can forgive him for his betrayal, and [*]Do you think there's a possibility that you can trust him again?[/list]Notice I didn't say anything about love. You say you love him, and I believe you. But the lack of forgiveness and trust will erode away your love over time, and you'll be even more depressed than you are now.

If you can't forgive him, you'll always resent him for what he did, you're inviting years of misery, and you should end your relationship now. If you can't trust him, you'll doubt him and worry every time he leaves the house, and you're inviting years of misery, and you should end the relationship now.

The person who knows you the best... is you. Right now, with your raw hurt, you might not be able to answer those two questions. So give yourself a month. No longer. That's long enough for the initial shock to fade and settle into the new reality of your relationship. By then, you must be able to honestly answer those two questions.

If you can answer "yes" to both, then you and your boyfriend may be able to repair your relationship and move forward. But if you answer "no" to any one of the two questions... well, you asked what you can do to go away from this depression. If you answer "no" and stay with him, your depression will never ever go away. If you answer "no" and leave him, your pain will fade, and you'll learn to have a normal, happy life again.

But if you decide to stay and he has a second affair, though - drunk or not - all bets are off, and you need to DTMFA. (That's "Dump the melon farmer already", the PG-rated version).

Above all, don't wait too long to make a decision so that both of you can move on with your lives. And be happy again.
