I'm thinking about leaving my girlfriend in her time of need.
Why would you leave your gf like that?
I heard she's been talking to some other guy behind my back.
I know you're upset, but it's wrong to abandon your girlfriend when she needs you the most. You should help her out instead then work out your problems.
Great. Just go ahead and judge me.
It's not that I wanna judge you, I only want to help you figure this out with your girlfriend. Unless you know for certain that she's been seeing someone else, then it would be wrong of you to leave her when she needs you. If you leave her now, she's unlikely to get back together with you in the future.
