Wow, someone comes on to share their experience of relationship success finding someone one the spectrum like themselves and being happy, and some people can only be negative and envious about it.
I for one am happy for the OP and her special someone, and hope they have many love-filled years ahead of them.
Perhaps people who can't be happy for others should take some time to think about why that is, and how that might be preventing them from finding happiness of their own. Envy, pettiness, and negativity are not exactly universally attractive traits.
