What do'you do when your mad over a girl, but she isn't single but the boyfriend is cheating
I have had a relationship with this girl in the past, and am mad over her! I think she has a slight glimpse of knowledge that I like her! But she isn't single, and her boyfriend is cheating on her. He is sending texts to other girls and not texting her. Saying ' you want to shag' and kissing other girls. She doesn't break up though cause I don't think she knows I like her, and cause she said she loves him!
What is my next steps?
What shall I tell her?
Please, I need URGENT HELP!!
Thanks very much x
