Hello mmarynuk and welcome to the forum. It is tough at times to be married and tougher still to be married and have a mental illness. I can't advise you on how to deal with your spouse, I can only say how my life with my spouse works and perhaps it may help. It might not help either, but nothing that follows is intended as a criticism. Part of this forums purpose is to allow people to vent out some of life's frustrations. Having bipolar can certainly be frustrating.
In regards to meds, Trillium can certainly help, but there is still a cost.

The other option is that sometimes your doctor may be able to give you or get for you some free samples to hold you over for a mth or so. Not all docs will do that, but some will.
My spouse is whale of a gal, but I can be pretty miserable when I don't take my meds. She has also learned that when I don't take my meds(hasn't happened in a long time now), I'm not the most reasonable person in the world, so she used to shut me out. There was no sense trying to have a discussion with me as I wasn't reasonable. I might have been right, but being right and being reasonable were ttwo different things when my moods were wrong.
Even today, I can still be hard to deal with if my moods aren't right, so my wife and I have come up with a plan that if it isn't earth shattering, need to be discussed right now topic, then we will let it sit till a pre determined date when we will be both cooled off. It took us quite a while to figure out how to do that.
We still have arguments, but we both try and stop them before we both start to say destructive things to each other.
I hope that you can find a way to try and get some meds and a way to settle your disputes before they reach the "I'm going to leave " stage. Those types of arguments are hard on everyone.
Don't get me wrong, I can certainly feel sympathy for you situation and I can understand you feeling very alone right now. However as has been said, we are friendly and we do try and understand, so please feel free to post on here. Then perhaps you won't feel so alone. Take Care. paul m
