I have been where your wife is... I have put my husband and kids through more than they ever deserved. I remember during my last manic episode I told my husband I did not love him. I was talking to another man I was using drugs staying out all night acting straight crazy.
What did he do he filled for divorce kept the kids from which is completely understandable.. He stayed away from me this lasted about 6 months. He even meet another women and was gonna move in with her.
After that he did come to me told me I filled for divorce the kids and I are gonna move in with my girl friend. I remember thinking on it for about 3 days. I called apologized told him I did love him and I would get help... It's now a year later I am taking my med and we are together like a family for what feels like the first time in my life..
I don't really now how to put it I feel like he saved my life.
I know this really don't help much just my story
