I don't know that you're being over sensitive, but you definitely are feeling frustrated, which seems to be manifesting itself in sensitivity. It may be time for a discussion and clear expectations agreed to.
I can sympathize with your SO. Of course she wants to keep you reined in. Comments you have made in the forum could easily lead someone to jump to the conclusion that you really wish you could transition, or at least be Charlotte almost all the time. She wants to keep this part of you confined and under control, so that she can keep the husband and father she enjoys.
