Olivia and Duke Orsino- Cruel or Just Honest?

In Shakespeare's Twelfth Night, Duke Orsino just can't seem to take the hint that the love of his life isn't interested in him. No matter what sweet gesture he does for Olivia, she pays him no attention. He dotes on her constantly, and it made it seem like Olivia was getting really annoyed with having to constantly put up with Orsino. She clearly wanted nothing to do with him (or any other guy,  for that matter).

This is why she makes the excuse that she is going to mourn the loss of her brother for seven years, and won't allow herself to see any other men during that time. I think this was actually a really clever move on her part. By saying she doesn't want to see any men, they will hopefully all back off, and she will be able to wait for the right guy to come along. Her plan doesn't work out too well though, because the men still fawn over her endlessly.

I think what Olivia did wasn't being cruel at all, she was just being honest about her feelings. She really did want nothing to do with Orsino or any of the other men after her. Why should she feel like she must do something in return for them when she has no feelings towards them? It's not like Olivia was being intentionally mean toward any of the men, she just knew that they weren't the ones for her. She shouldn't have to be pressured into doing anything, if she doesn't even really like the guy!
