Nope, never hangs out with them alone. In fact she's
always getting on me if i leave her alone when at my family's
house or at family gatherings.

I think she just fears that she's so Boring and that she has nothing
interesting to talk about and fears being unliked by my Mom. Not
so with my Dad, she loves my Dad and he loves her. She's more herself
with my Dad, not so with my Mom.

Yeah, I knew she was Shy when we 1st met and I come from a background of shyness so i understand. Maybe we just need to hang out
with them more so she can get to know them more.

She's never brought anything to my attention (and she would) that
would make her feel uncomfortable. i seriously am thinking right now that
she just needs to hang with my Mom more so that she'll feel more
comfortable.

It happens this way with friends though too. friends of mine that she considers
"cool", she's afraid to hang with for fear of having nothing to say.
