Most Helpful Girl
I'm not precisely sure about others, but I stop talking to my ex because keeping them as a factor in my life would typically be problematic later on. I'm not about bullshit and I'm not about spending even the most minimal thought, effort, or energy on people who's presence doesn't hold a certain ACTIVE importance to me. Yeah, at some point and time, his presence held a highly active importance to me but that significance is now inactive and motionless. A former relationship is an unmoving bond that just stays still and doesn't stir any emotion so why keep them around? Seems pointless to me.
