My fiancé has “bro days” but it’s hard for him to even spend 2 hours with me..

For example, on Sunday we had a date and went to get lunch, and he took me home straight after bc he was tired. Then proceeded to play video games and hardly speak to me for the rest of the day. But then when he hangs out with his friends, he can spend HOURS with them. Playing video games with them for maybe 4 hours then going to eat and maybe going somewhere else like Dave & Busters. I ask to do stuff like that all the time and we’ve never once done it.... am I overreacting or should I say something? I don’t want to sound like I’m jealous and want every second of his time but I’d like to see him for more than 2 hours 🙁
