As others have said, you need a more outgoing person as your other half, as they can push you to do more things, but this isnt nessercarily bad as once your fully comfortable with your other half you will go to these places outta your comfort zone with them and they will usually ease you with their prescence anyway.
It sounds silly to have a person non-sa, as they don't usually understand... for example I try explaining everyday my anxiety and mental issues to my outgoing, amazing, hard-working, carefree boyfriend... He knows the score, he knows i'm not normal, but can't understand to some extent. But it can work, I promise, with a few disagreements (but everyone has disagreements). We have child though, so makes it more of a thing for him to want to be with me.
There was one bad time though that after an argument my boyfriend was saying i'm mentally ill and asking if I was going to overdose that night, which has made me even more self-conscious about the illness.
