The decision is ultimately yours.
For me, I would have bushed her by now.
What's the point of dealing with a girl who most likely
is giving you signs she is still not over her ex?
Keep in mind her ex spent 5 years with her, while you have only spent
8 months.
Soon as a girl tells me that, I'm thinking "Yeah she's either fukking her ex behind my back or she is going to eventually." But again, that's me.
That's an L waiting to happen and how do you know this bytch is not doing some dirt behind your back?
Do what you feel is right.
