My wife left 10 weeks ago and hasn't talked to me since?

If you love her and want to try to work things out go confront her and make her talk to you. You have the right to know why she is doing this. Tell her that if you are doing something that is upsetting her that you can't fix it if she doesn't plainly tell you. She may have been sending signals or trying nicely to tell you in the past, but I have found with my husband and most men, that you have to just about beat them over the head with the problem to get them to finally hear it.
