Listen, if you want to get into a hotwife or cuckold relationship, than you're doing all the right things.
If not, grow a pair, say you will only swing with a couple where you at least get something.
If she still wants you to wait for her, at home or at the club, while she fucks a single guy in private, than it's time to find a new gf who will really care about you.
If any of my SO or gfs had said that to me, since just saying it shows intent to have her cake and assume I'll be there waiting when she's done to keep on taking care of her other needs, there would have been no discussion, no negotiation, just the door!
When will people realize that sometimes their SO is just playing them and pretending to care when they really do not give a shit about them?
