well i was going to suggest to make sure that your spouse's sudden "let's see what my sexuality really is" thing might not have been a very common bad misunderstanding that going through gender issues should somehow automatically mean going through sexuality issues as well.
however, having read that last post, it seems like the whole thing was kinda beyond that already. in which case, good for you for sticking by your decision, and it's probably for the best, as you sounded a little fed up to the teeth with things at any rate, and that's no good in a loving relationship, for either person. and failing to answer calls... well... i don't know what's going on with that. i feel sorry for you and happy for you at the same time, it's... strange. i think it's for the best.
please know that i'm not very good at wording things oftentimes, and i think i sound overly self-assured in this reply, and i want to tell you, i'm not, please don't take my opinions too seriously, just averagely.
