Several problems here:- - 1) That does not sound like a very healthy relationship if all it takes to get the two of you arguing is a mere video game - 2) There is far more to a relationship than appearance, cheesy I know, but the cheesy stuff tends to be the right stuff in these situations - 3) You are, I assume, a fully grown independent, single-minded, conscious individual who can make their own decisions, exercise it - 4) People who think they are dominant over their partner like that most often are not used to retaliation. Respond; simply tell her, "you know what no I am my own person and I'll enjoy this game if I want. If this simple little thing is seriously what you are most concerned about in a relationship, then its over already." P.S.: I know Number Two is very cheesy, but I think its important. When I first started dating my boyfriend, he certainly wasn't the next big Calvin Klein Model, but he had more important qualities than that; he was very pleasant, funny, quirky, relatable, and he remains like that to this day. He has since then though become rather fit shall we say so I know the best of both worlds now ;)
