wow. wow. WOW. I've been following your posts for months now, and now things are starting to make sense... I have several close friends who are bipolar, and this is classic behaviour. Its just too bad its been at the expense of your marriage. I'm still in shock at the whole thing. My H has recently started taking antidepressants, but is in denial that depression could actually be contributing to his unhappiness... we'll see how that pans out. Do you know if she is on meds yet? All I can say is keep doing what you're doing, but she is the mother of your children, and this could be really tough for them. If you are the first person she has shared this info with, then she will need all the support she can get. It took one of my best friends several years before her doctors got her on the right meds, and the right balance of meds. Its a long tough road. Maybe you can do some googling, talk to your own doctor etc just to see how you can support her (even if she doesn't know you are doing it). I can't imagine how you are feeling right now, so you might be thinking 'are you crazy, im not going to support her' lol.. But if not for yourself, for your children. They deserve to have the very best parents they can have - mother AND father. Also, I agree with the above, don't beat yourself up about it. As much as I hate to admit it, I could see myself doing the same thing. Anyways, hang in there.. just be prepared to see a lot more manic behaviour. She will likely get worse before she gets better. Good luck!
