But meh overall. I don't think it's that deep.
Her and Ginuwine were never really close to begin with.
Timbaland was possessive and jealous over his muse.
Missy, probably suffered whatever Timbaland did at the hands of Barry and his shady business. Not being paid, etc. Li was probably stuck in the middle and that's why they didn't submit a lot of work for her 3rd mess, I mean if they weren't getting paid correctly I understand. So yeah probably just nuances of mixing friendships and business. Li was def put in a position to straddle the fence but sis has to keep it moving, keep working. I think it all just happened too fast and a mere falling out (which happens to all friends at some point) didn't get a chance to be resolved
