should I be concerned?

so I love my bf, he’s great and treats me really well in person. however i’m seeing a little bit of something i’m not liking and I need advice cuz maybe it’s just my head.

so throughout the week we can’t see each other bc i’m in nursing school and have to study. I have a lot of rough days because it’s so hard and stressful. my bf tries to say a few encouraging things but that’s really it then he’ll disappear for hours playing video games. that’s ok with me but sometimes I wish he’d be a little more concerned and just say some romantic things? idk. am I just overreacting? I had an awful day today and everything is ticking me off.
