It's not good not to play games with your girlfriend, which will easily hurt her young mind.
First of all, I'm a girl, but I'm still different from your girlfriend after reading the question description. You don't want to play with your girlfriend because she just started playing game dishes. Although I'm a vegetable, I've been playing for several years, and my boyfriend is similar to me. My boyfriend doesn't want to play with me because I play with my brain and value winning or losing.
Besides, he doesn't like to play sports himself, so my boyfriend doesn't want to play any sports with me. Watchman only plays fast, LOL only plays rough fights, and Storm Hero only plays man-machine. As for dota, I'm sorry I only play man-machine, so I'm not sure about the specific cooperation.
Although the reasons are different, both you and my boyfriend don't want to play games with their girlfriends (although my boyfriend just doesn't want to play with me, I also want to play sports sometimes). My boyfriend has handled this aspect quite well. At least I don't think he is perfunctory, so he just said that he doesn't want to match or play sports. I think it's easier to understand honestly.
However, it may not be easy to say about your girlfriend's food. It is a fact that everyone is willing to play with strong people. Since you don't play with your girlfriend and just want to play games quietly, you can tell her that you just want to play games by yourself, which is to relax your mood. There are many things you can do with her. This is your own corner. I think it should be possible. But if you don't play with your girlfriend, you can play with others, especially your sister and your girlfriend.
oh, yes, and if your girlfriend definitely wants to play games with you, but her skills are really not up to standard, you can buy some cooperative non-competitive games, such as raft, Famine, gta5 and Forest. I still have a good time playing these games with my boyfriend.
