If you're interested in hammock camping with two people, I'd suggest looking into two single hammocks with a spreader bar system. The ENO Fuse Tandem is a good place to start - You'll both be more comfortable than sleeping in the same one. If you just like having a larger hammock for yourself, I'd probably just return and get a single to be honest. You're not going to give yourself more room when hammock camping by having a larger hammock since it will wrap around you a bit when you're sleeping and save some weight at the same time. Hammock camping systems aren't really designed to be flat like a lounging hammock you'd see in a back yard which is why gear for it tends to be pretty specialized like straps that don't harm tree bark.
Good luck on your hunt!
