Relationships are challenging when you are bipolar. As much as we would like those we love to understand the disorder and why we do the things we do it's a pretty tall order. I've been married to the same man for 23 years. It is very difficult for him to cope with all of the ups and downs that come with this life we live. If he loves you and is able he will stay with you and help you through it. Good luck and hang in there. It does get better (at least they keep telling me that).
