I have feelings for someone other than my wife
This is a serious issue. I assume your wife isn't aware?
She isn't, and I attract nothing but bad luck.
I get that we don't really have much control over developing feelings for someone. You're married, though, so I recommend not acting on your feelings.
I already expressed my feelings for someone else, and he turned me down.
Then I believe it's best to just stop trying to pursue this other person. Marriage is supposed to be eternal and full of faithfulness, what would your wife think if you were actually seeing another person, especially a man? Maybe you can sort out your feelings and sexuality with a therapist.
