Look, I have bipolar. Its not bipolars fault that he is being a jerk. It can sometimes kick in and be the cause of something extreme happening, but not going on and on and on for weeks at a time. It is possibly a bad med reaction - that can cause a lot of trouble (but he is getting off that med, so that might help). But if he isn't see-sawing by trying to sometimes meet you half way, he is just a jerk that is being a big baby and either not caring, or using his illness as a reason. Its not a reason. I am bipolar female age 50, diagnosed at age about 15 or 16 the first time. I can be a pain, but I also turn around and am the most wonderful kind sweet thoughtful person.

Bipolar doesn't mean MEAN. Its him. And he can change, he needs to own it.
