I don't play games. Also, knowing the nature of men, I don't over-think it. Men are basically simple creatures (I don't mean stupid, just uncomplicated) - they are visual creatures, and don't tend to get wrapped up in the touchy-feely emotional side of things. Knowing that, I make sure that I pull myself together every day (makeup, hair, clothes) in such a way that I'm visually appealing to him. I don't get jealous (honestly I don't notice or care if he looks at other women, or goes to a strip club with the guys, as long as that's as far as it goes). I think that when we think jealous thoughts or act in a jealous manner, that is a big turn-off to most men.
Aside from that, I do find it annoying that men are so into sports on TV. My husband does it, too. I just wander off and go do my own thing. I think men are pretty much hard-wired to like sports (battle! grrrr!), and expecting them to abandon it because we want all their attention is a losing proposition. He likes sports, I like shopping, and neither one of us will ever love the other's hobby. I accept it and move on to something that doesn't drive me crazy. :)
I guess the way I keep my husband's attention is by being good to look at, and then not giving a damn if he pays attention to me or not. Reverse psychology, I guess?
