Bipolar is a tough illness to deal with, not just for the person with it, but for those that you are around. Your wife has obviously become accustomed to the Bipolar you, and is not used to the medicated you. In time she will see that the meds are helping you and she will get used to what you are like mentally well.

As far as how your marriage is now, I highly suggest that you two involve a marriage counselor to see if you guys can fix your marriage. Marriage is hrd enough without involvement of mental illness, and with you having bipolar its even harder. Before yall make a decision to split, you should make sure that you have done absolutely everything to try and help things out.
