Been seeing this gal for awhile.

She keeps saying she loves me.

She has an old "best Friend" who's a guy who she used to sleep with.

They catch up for hours on the phone and stay up late

She says she doesn't think of him romantically.

But they used to sleep together. As recently as last summer.

She says I don't have anything to worry about.

I feel like she must like the attention at the very least and is probably still into him, and would fuck him

I should break up with her right?
