Got a hint for any ladies that may be in similar circumstances. Complaint =! incentive to change. No one wants to spend time with someone who's always negative. You want attention? Attract it. Offer positive alternatives. Maybe even try to join them from time to time. Hell, women have been feigning interest in sports for ages. And maybe - just maybe - talk to the guy and see if there might be a common interest between you besides just sex.
Or leave with grace, dignity intact.
I'm serious. That's a perfectly viable option. If he no longer is interested in you, yelling about it isn't going to magically change that. If you can't, or are unwilling to draw his attention away from his hobby, and you won't join him in it, what purpose is there in drawing out the inevitable? Avoid the years of frustration and animosity. Just go.
