Frustration

Hi my name is chelsey and im 21 years old my bf n I have been together for 4 years we also have a son together who just recently turned 1. My bf n I lately have been off you can say lately we been arguing a lot n since he works a lot n has one day off it's hard for us to hang out but I figured on his day off we can do something together but he Just wants to go golfing or hang out with his brothers an it makes me sad at times because it's like I'm always pushed to the side an even in the bedroom we haven't been together because he's always to tired but when I try to talk to him bout things he thinks I'm just nagging but I don't know what else to do cause the times we do hang out or we do have sex it's great ........ Im just in need of some advice
