Hi there! :)
Good to hear your story and welcome.
Although I married a RM, my sister didn't and my brother is not a RM but they are both married. :)
And anyways, just because you go on a mission it doesn't mean that you are more special or more spiritual than people who haven't been on a mission. I know and have heard of plenty of guys who went on missions without being truly worthy to go and whilst they were on their mission they were not 'good boys' either. And then you have guys who haven't been on missions who are very strong in the church and they hold very high standards and marry in the temple... So the 'RM label' is not a guarantee for 'quality'.
What matters is what kind of person you are now, how you are developing, whether you are keeping the Lord's commandments etc etc...
Although I'm in no way advocating not to go on a mission (for some it was the best thing they ever did and we are urged to be missionaries) I am saying that just because you don't go on a mission it doesn't mean there is no hope for you to ever get married!
There's always hope - perhaps you just need to look elsewhere... like a different country perhaps.
(I'm from England and I know plenty of single girls here...lol) :)
Anyways, I hope you enjoy this site as much as I do! :)
