you're quiet ... you don't talk.. blah blah bla

Ok.. cut a long story short.
I suffer from mental illness, social anxiety..
I attend a group every Thursday which is a spiritual group where we receive reading etc.. (big step for me) as I don't normally do this kind of thing .. my fiancé kinda pushed me(which I'm glad)
One of the people that goes there invited me and my fiancé over for food.. and I've met her husband 2 times...
And he tries to belittle me.. just because I don't speak as much as everyone else who attended
"You're so shy" "do you ever talk" " it's the quiet ones you have to watch" etc etc
I just laugh it off and speak to my fiancé.. and others who speak with me and then when I just sit there for a minute he says "oh shes still quiet"
Today he was at the group and I didn't see him in the kitchen and he said "oh here she is the quiet one,,, and she didn't even say hello... and then in front of everyone came over to me and put his hand to his ear... to say I can't hear you sort of thing. So I just laughed and he continued to do it.. so I walked away. 
It's very embarrassing for me and makes me feel so small.
Yes I am quiet, and he is aware of that there's no need to keep pointing it out.. his wife has said I'm the quieter one of the group so I don't see why he keeps on at me all the time.. it making me want to stop talking to him less and hating myself and feeling more anxious and insecure than I already do.. with such big characters there. 
Anyway.. he joined in with group and we had to say stuff about each other and his wife said to him.. that he isn't a very good talker and he's a bit shy and everyone agreed .. and he went all embarrassed and just said " I suppose"..( he doesn't speak a lot either ) so why does he make me feel so small.. and more insecure if he's quiet himself. 
There's nothing I hate more than someone repeatedly pointing out the flaws in you.
Hate it!!!!!!!!!!!!!
