been there done that
it was the most successful relationship ive ever had with a girl, and when we first met it was awkward and we both aknowledge how awkward it was for us, are first meeting up wasnt are first date in truth that was are second meeting up
i choose to treat it as if i was meeting a relative i hadnt seen in a long while, and that there apperence maybe different than u remember, and funny enough she told me she treated it the exact same way
however she was considered an NT, though late in the relationship i put all the pieces togather and realized she had aspergers
the best thing i can tell u is go in with an open mind expect the unexpected be ready for questions and hav questions of ur own, show that person the best u, u can be
best of luck
