With a couple, with one person transitioning, communication is really critical. It is important that your partner respects your feelings, really important. I will relate two things that happened early on in my transition. One, once I decided to transition, I spent a lot of time and mental energy on it. It was quite consuming and I had to watch myself to be considerate of my partner. This part does not last forever thankfully. Another thing is the hormones did change things. I became finally more hopeful, cheerier on the whole, and definitely more emotional. I became a nicer person even though I was a bit needy for a while. I can't speak to multitasking. I am not sure I understand what it is that your partner is doing / not doing that is causing you distress. It definitely is a stressful thing, so it is not surprising that you would feel unsure about the future. I don't think anyone with dysphoria really gets what transitioning is until they do it. It is not a cure for all problems, that's for sure. Your partner might have some fantasy thoughts on what transition is like until reality hits. It is hard work, is damn inconvenient, and requires sacrifices. Unfortunately, for some folks like me, there is no other option that allows the keeping of sanity. I would wish you both the best of luck though.
