I don't think Bipolar alone can be blamed for unfaithfulness. But I think having a manic episode makes it more difficult to stay faithful if there are already problems in the relationship and you're already feeling tempted.

I'll admit I have been married four times and unfaithful to three of them. And before those marriages and in between them I was promiscuous. If you knew my history, it would probably make sense.

But all of the unfaithfulness occurred during manic episodes. I take full responsibility, manic or not. There were problems in those relationships where there was infidelity from the other person or not feeling my needs were met. I think I wanted to hurt them, because they hurt me, too. Because mentally, I was like 8 years old.

I am remarried for the fourth time and I did have a manic meltdown and was unfaithful a couple of years ago. I thought for sure I was leaving him anyway, but we worked through it and it's the first time in my life that I know with certainty I will never be unfaithful again. I was finally able to see just how much pain I caused with my actions and I would never ever put anyone through it again. I also have a deeper, trusting, more spiritual and respectful relationship with my current husband. I never had that before.

I think, ultimately, not having your needs met (emotional, physical, mental...whatever it is you need) leaves a door open to be tempted. And being in a manic state makes it just a little easier to walk through it.But if the relationship is strong, it can easily withstand the manic times with faithfulness.
