Video game addiction

I have had it. I am literally about to lose my mind. For three years, i’ve supported him, supported this hobby, played with him, encouraged him, cheered him on, watched him stream but im starting to think it’s more than just a hobby now. it is affecting our relationship. I feel so alone. he pretends to take a nap to avoid doing anything with me but really he’s playing the game. he will watch something with me online (we don’t live together) just to get spending time with me out of the way so he could game. he just spend $5K on a new computer so that he could have better graphics. he barely flirts with me anymore, he’s on autopilot mode with me now, says I love u but it just feels empty. he won’t even text me goodnight anymore if he’s gaming on the weekends. i don’t know what to do. not to mention, when we do watch netflix together, i hear him playing his game on the side. so he’s never really giving me his full attention. I want to be supportive of the stuff he loves and I like to game too but I just think it’s past a hobby now. is this normal/sound like a hobby or addiction??
