Relationships are hard enough when things are "normal." Add in the roller coaster ride of being BP and you have a lot to deal with. I was married for 20 years married at age 21. I know for a fact at times I drove my wife crazy with the ups and downs. My BP was fairly mild, so I was able to work and have a solid career. The worst was the depression....I could not even function.

I had my first major depression at age 16, another at 21 and again at age 30...never got help or treatment....just got through it. My wife convinced me to get help and I did, meds and tons of talk therapy. Took about a year before I was diagnosed with BP.

A few observations:

1. You have to remember to take care of yourself first and foremost. Folks with BP can put others through hell. It's not intentional in most cases, its what we live with. This is why meds and therapy are so important.

2. If you want to take the journey you have to remember that her past behaviors will more than likely reoccur (you have to be prepared to accept it if you want to have a relationship).

3. You might want to pick up a few books on BP if in fact that is what she has. Books about living with someone with BP.

4. Folks with BP usually have a very difficult time accepting the fact that they are BP, so she has to be willing and committed to doing the work. The only way to know for sure is if she get a proper diagnosis. Many of the behaviors you have describe sound a lot like BP.

Best of luck!
