Nyme:

She still needs you otherwise what's your number still doing in her phone? All dat story abt calling her cousin "RAY" is pretense. Wait n see if she won't call again.

It's a catch-22. If you delete the number, you won't make the mistake of calling them; but if you still have the number saved with their name, you can quickly recognize the caller when they call you.

Anyway, considering all the information provided by the OP, sounds like the Ex still wants to stay in touch.

U're now her cousin Ray! No more cainin,

Guy don't dull. If υ̲̣̥ r still interested in her, just invite her to ur place and bed her. Trust me she still loves you!
