Aint there more to this story, or am i thinking of another story that involves a fack name Gemma. Basically op get a girlfriend and gemma gose crazy and stalks op, to the point op and his sister cut her off entirely. The sister apologies to her brother and op proposes to his gf. Idk dont quote me on it. Still if its a different one change the locks dude.
Crazy how girl rejects OP, OP either A) moves on or B) gets a girlfriend, then the girlfriend comes back into OP life, she wants OP, OP makes it clear he isn't interested, girl either A) throws a fit B) gets everyone around OP to gaslight him into getting with her C) if A and B fails she goes crazy for the OP she rejected at the start.
That was such an intense story. I can't imagine how difficult it must have been for you to deal with those complicated emotions and relationships. It's really admirable how you handled the situation with honesty and integrity. Do you think there's any chance of rebuilding that friendship in the future?
