Am I being unreasonable? I feel like I'm the one comprimising

Hi I've been with my bf for only 3 months.

I'm 30 next month and had enough bad experience in relationships to see when it won't work.

Me and my bf are so good together and I feel in so many ways I have met a good match.

However we are both gamers and about a month after us dating he got back into playing an online multilayer game which in itself is fine. The problem lies in that he will play with every spare bit of time he has and the only quality time I get is when we go to bed or I've specifically asked him to come off to spend time with me.

We've talked numerous times about this already about how I feel less of a priority and how I feel he dictates our relationship and how we spend our time together.

I have got to a point now where I will no longer ask him to come off, he offers to come off after 1 more game which let's me get excited to have some one on one time with him only to find he carries on playing for another 2 hours and then he wonders why I'm upset.

I can't help but feel like I have a roommate who I have sex with sometimes. When he does engage with me he is so attentive and giving.

I just don't know what else I can say to him. We live together too.. I know there's plenty more I can say but that's my condensed version for now.

Many thanks x
