What worries me the most is that your partner hid his bipolar disorder from you, instead of being upfront about it. In my case it's my best friend who's bipolar, not my husband, but even with it being a friendship rather than a relationship he was extremely upfront with us about his problem. He told us what to expect, and I think he also expected us to run for the hills when he told us, but of course we didn't, lol.

Sometimes my friend's behavior has been a little off the wall, aggressive and a little emotionally abusive when he's in mixed states. We get into some fine screaming matches when we're both having bad days. I've never felt particularly threatened, though, and the thing with my friend is that he's SO apologetic afterwords. 95% of the time he's wonderful, so I just put up with the other 5%.

But my friend is honest, and he wants our help and accepts our support. I don't see that in your partner, quite honestly, and I'm not sure I'd even be around my friend if there were children involved. It's hard enough to understand what's going on as an adult, the unpredictability would have to be terrifying for a child.

Which I guess is my long-winded way of saying I don't think it sounds like your relationship is going anywhere very good. Starting from a place of deception is just not the way good relationships are made.
