what’s happening to us?

my boyfriend and I don’t have the best home life anymore. We used to be so happy and content just goofing off with each other and talking about our days... followed by being content binge watching nextflix together. We moved to South Carolina and our home life just seems dead. All he does is play video games and I’ll be on my laptop doing my own thing next to him. We aren’t silly anymore and it all just feels serious. The question is always “what do you want to do?” “Idk... there’s not much to do” and that’s it and then we do our own things. He’s never in the mood to watch tv anymore. Can anyone else relate? I love him with my whole heart but it doesn’t feel exciting anymore. It seems like we are just living together and not e joying each other.
