8 months together and being pushed away...

I’ve been with my girlfriend for the past 8 months. She means a lot to me, love her to the moon and back. She likes playing video games and recently I’ve noticed this trend that she’ll play for the majority of the day and then fall asleep. When I want to cuddle or spend time with her, I get pushed away. I know she bought an expensive game (RDR2) & wants to enjoy it, but I feel like I’m in the background, only noticed when she needs something. I’m not looking for attention, just her affection... like the old times. What do I do?
