bi-polar??

has anyone ever dealt with someone or had a spouse who may be bipolar? I've always felt like my husband may be but he will never admit to it. I love him dearly but sometimes I don't know how to deal with the extreme ups and downs in our relationship. he can be the nicest most loving man in the world, or your worst nightmare. if something sets him off, watch out, and it's always directed towards me. he is starting to do things that I strongly disagree with in front of our 2 year old when he gets a bad temper, like swear at me and call.me names etc. I'm sad and I don't know how to handle this. Just looking for advice maybe from anyone who was dealt with something similar
