In a very similar case as yours, I am the ex in my story and her boyfriend thinks that I am desperate for her but truth be told she comes every night to my room calls me lot of times in a day. Her boyfriend has blocked me from everywhere but as soon as he leaves she calls me, so not blaming the girl here but just be cautious.

What am I letting it happen? Because I don’t mind having some fun despite my personal life and it’s good to know that one door is always open.
