Advice please!!!!

My boyfriend and I have a pretty good relationship. However, there are some things that bother me and I’m not sure how to bring them up. He’s an only child who still lives at home at the age of 30, which is whatever because everything is so expensive where we live. He pays rent and bills and pays for my schooling so I don’t even think twice about living at home. I am a mama to two kiddos from a previous relationship and I’m the oldest child in my family with many younger siblings. Here’s the stuff that’s bothering me.

Every time he pees, he doesn’t flush and leave the toilet seat up. He wants to be the best of the best all the time meaning, if we both buy a toy for my son, but his was more expensive and cooler, he’ll want me to give my toy first so he looks better than me. He doesn’t do his own laundry, make his own bed, doesn’t pick up after himself because he knows his mom will do it all. When he gets home from work, he throws his work clothes on the stairs to the basement so his mom can pick them up and wash them for him. Mind you, she’s in her late 60s and walking up and down stairs is harder for her. There’s a few other things but they all have a similar or the same theme. He’s a great guy honestly. We just were raised different and have very different lifestyles. I take care of my two babies, clean my house, pick up after myself and get groceries, all the normal mom stuff. I guess just watching him act like the only thing that matters is himself in a way, is a really big turn off. Does this make sense? Maybe it’s not even worth saying anything about but I’m just curious what everyone else thinks.
