I'm sorry you're going through such a hard time. I don't know the particulars of PCOS but I'm familiar with not having your concerns heard by doctors who are too pompous to really address them. It's ok to feel guilty; in situations like yours its normal. It's hard not being able to share that part of yourself with your partner, so that's why I'm stressing this. Please don't blame yourself. I know things aren't simple but have you considered looking for second opinions? I say this because this seems to be causing you major discomfort & you indicated you feel it's affecting your relationship. Also, sometimes doctors within the same specialty have differing opinions & solutions, so there's probably other possibilities for you. I know this is hard for you; hang in there.
