lol must be "true love" if she wants to change you right after becoming a couple. it's even more sad that you're willing to follow that. either you have fun with an oppressed life or you man up and tell her that it's your hobby and you decide how to spend your free time. to make her understand, tell her if you stop gaming altogether, she needs to stop doing her favorite thing as well (I dunno, delete her FB account or something).
Dump her now. If she is making you give up something you love instead of trying to work with you on it..then she wants to change you into what she sees fit..instead of loving you for who you are. It will not end well..trust me. Also picking your new years resolution for you? Controlling.
An excuse is the sauce fools spoon over failure to hide the flavor of their own incompetence. PSN: Taran_Omega / Steam ID: tpanciera
