Hello Jenn. When you said " - he may not know it but the guilt he causes me to feel whether intentional or not - feel like I should just leave the relationship sometimes ".
I can understand your feelings. I've had the same feelings a fair number of times(guilt and thinking I should leave). I don't know you or your fiance, but I'm glad that I stayed with my spouse( and that she allowed me to stay LOL). However as understanding as my spouse is, sometimes the frustration of my having bipolar does boil over into the occasional unpleasant argument.
Fortunately we don't have those arguments very often anymore, but it took at lot of work to get to this point. BTW, nothing here should be taken as a criticism, they are just my own views, gained through my own life experiences..
I can only say that bipolar is a difficult illness to have and sometimes it's difficult for my spouse to live with someone who has bipolar.
Of course that's just speaking for myself, I know that all of you other people who have bipolar are wonderful people who would never cause anyone a moment of anxiety LOL.
However I understand the guilt that bipolar causes all to well. It shouldn't as bipolar is a legitimate illness and we are mostly good people with a bad illness, not bad people with inventive excuses.
But as you and I and many people with bipolar know we all suffer enough guilt on our own and we don't need someone reminding us of bad things that may have happened or good things that didn't happen because of our illness. Take Care. paul m.
