need to rant for a minute!

so we have a little jack Russell, corgi, chihuahua mix pup and we took him outside for a walk and the ground got hot on his paws and he was whining and lifting his paws up so I simply ask my bf to pick him up cause i cant bend that low to grab him n he freaks out and says im useless......okay I'm pregnant. Everytime I ask him to do something small it's a issue and turns ti a fight but Everytime he ask me to get him something or what not I bow down and do it without complaining....ugh don't know what to do
