This is 100% BPD.
They don't have a personality of their own, so they take on the other persons, "mirroring" and they can get extremely co-dependant and clingy.
They can be fun, but when something sets off their seperation anxiety they go fucking nuts trying to get attention at first. If they keep getting iced out or ignored eventually they "split".
Theres no in between for BPD's, you're either the greatest person ever or you're the personification of all evil.
A BPD psycho on a meltdown is capable of anything, trying to frame you for shit, trying to embarrass and ruin your reputation, right up to driving their car through the front of your house in a screaming rage, or worse.
Don't stick your dick in crazy is a saying for a reason.
April right now is showing all the signs of going into a BPD meltdown.
Nicks stuck his dick in a hornets nest, and if he tries to pull it out the hornets are going to erupt in his face.
