Is the guy I'm seeing possibly bi polar?

The current guy im seeing has a pattern of drastically changing his mind about me out of the blue and it's very confusing to me. One minute he will be all warm and friendly and will say things like "I see myself having kids with you" , "I told my friends you might be my wife" and then days later he will be super cold and distant out of nowhere and will say hurtful things like "I don't see you as my wife so we should just end this before I hurt you" . Then the next day he will say he just got scared and didn't mean what he said and he will be all lovey dovey again. Then again days later he will get all depressed and tell me he has doubts about us. I know he struggles with anxiety, depression, and mood swings... but do you guys possibly think he could be bi polar? I don't know what else to think because his behavior with me is never triggered by arguments, him seeing other girls etc. It just kind of happens on its own out of nowhere in this repetitive circle. I've never dated a guy like this and I'm very close to just cutting him off because it's a Rollercoaster.
