"Went through my phone when I was asleep and texted every female (I save everyone on my phone using their full government names) that she was my girlfriend and they’d better back off or she’d come after them and do them physical harm.
The thing is, the only numbers I have on my phone are all family. So I recieved multiple texts and calls the next day asking if I was okay or being held hostage."

That is something I will never understand.
There is this thing called infatuation - it is like a drug that makes people almost unable to find minor faults with each other until it is over, it can last for between 1 and 3 years. All the redflags are obvious in hindsight or from neutral observers perspective, also if someone was burned previously they will learn to spot the early signs out of necessity.
