Is this semi-normal for bipolars to behave this way? You should be the one who she goes home to, not him. It's very sweet that you trust her, but if she is having episodes, she is not in her right mind and her judgement is impaired.
This is my first relationship with a bipolar person. If you can, try to get her to open up to you, and better yet, get her to see a doctor.
Community Q&A Bipolar disorder can be tough for the person affected; some people learn to control it, some don't, but it's important to understand how they're affected and how you can help them.
Dating someone with bipolar is no different to dating anyone else.
As a bipolar person myself, i know that when being silly enough to get yourself into a situation where another man may want something from you, it's hard to then say no.
And a bi-polar individual must have alot of support and be able to trust their significant other.It's sounds to me like she's using avoidance to not face guilt feelings.
