My SO infuriates me. I have my nephew for the night and he's currently in he middle, apparently my SO can't get comfortable cause my nephew is in the way. so he moves to the bottom of the bed. when he invites his baby cousin I don't complain about how much room I got. and he'll lay at the foot of the bed when his cousin is here and leave me with no room to sleep and be comfortable, mind you I never fucking complain about it. it's always something when it comes to me and my family. he wanted me to put my nephew on the edge and stick my grown ass in the middle. Wtf does he expect in bout 8 months?
