There is a fine line someplace about expectations.
when we were looking for singles guys for MFM, i would feel that if we actually met, i was obligated to let him have his way with me .. took some reassurances and meeting a couple of jerks to get over that

but as long as you are honest, youre never obligated..
. What if there is only a one-way attraction there? Can lead to hurt feelings and awkardness.
yes, i think everyone needs to watch their feelings, and not expect too much ... there are people who will use that to try to manipulate you,
if you get uncomfortable and want to back out, the others should be understanding ... of course, one should back out with tact ...
2. If you get cold feet can hurt feelings. The other couple might have expectations and may have passed up other opportunities for you.
thats just the chance they took to talk to you

not your problem
3. You're on someone's home turf. This can make the visitors a bit uncomfortable and can make the hosts feel an extra obligation even if they have no real interest.
true, theres that fine line again ...
