Video games

I’ve been dating my boyfriend for 5 months. We are both 17. He plays this video game that he LOVES and he’s in top percent of players. He told me his family makes fun of him for playing and it makes him sad so I try to be supportive. I dressed up for him and did my hair/makeup for our 5 month nice dinner and he left right after dinner to go play. I was very upset and i don’t know how to talk to him about it. Sometimes I feel like he wants to play the game more than be with me. What do I do?
