Well it depends on the situation.
If you only play casually and for fun but she hates the gamer lifestyle then I'd drop her immediately, ain't no woman going to change that about me and you shouldn't let someone do that to you.
However if you'd rather play Destiny than spend time with your girlfriend that's on you bud. You need to spend time with her if she's worth it.
In the end though, a girlfriend has no fiscal, physical, or mental control over your life and decisions, I just hope you make a choice you won't regret. I'd choose the love of a girlfriend or a wife over Destiny any day.
Its a classic power play. If you stop gaming what else will she tell you to stop or start doing?
As long as youre handling all of your responsibilities then -blam!- it and -blam!- her.
These dudes on here saying its pathetic to lose a girl over a video game are missing the point. Its the principle....
Is she uncommon?
If so, useless. dismantle her.
Is she rare?
If so, dismantle her. You'll get some nice parts from her.
Is she legendary?
If so, what are her perks and how much will she benefit your light level?
-If she is no benefit to you, dismantle. You could use those legendary marks.
Is she exotic?
If so, which exotic is she? Will you ever find another exotic as rare as her? Or is she just another Alpha-Lupi?
-If there are other exotics like her, dismantle. Go for another exotic that doesn't waste a slot.
