Weren't or wasn't? I'm not clear on which to use in this example.?

Wasn't is the correct word to use here. Weren't is used for plural, but "I" is singular so wasn't is correct. Here is how "weren't" would work:

"We would feel sorry for you if we weren't so happy"

If you are happy: If I weren't so happy, I would feel sorry for you. It doesn't matter which order the clauses are in. The "were" doesn't indicate plurality in the present tense; it indicates a contrary-to-fact, hypothetical situation. People will understand you whichever you use.

Weren't is correct -- your sentence is a hypothetical, because it starts with "I would," thus the hypothetical "were" must be used. "Wasn't" implies something that happened in the past, i.e., "I would feel sorry for you if I hadn't been so happy."

Hard one! I think wasn't. That sounds right to me. Again, I THINK were is present tense and was is past tense. Wait for more answers.
