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

Does she know that he's cheating? If she doesn't then she has the right to know. But coming from you might be a bit weird because if she knows that you may like her then she might just think that you're trying to break them up

You can't do anything as long as she's in a relationship. You can let her know that her boyfriend is cheating, but telling her you like her isn't appropriate as long as she's still with him.

It doesn't matter if he's cheating you you think he isn't good enough for her. All that matters is that as long as she has a boyfriend, she's off limits.

You mind your own business and let her find out for herself.

If she knows you like her she will probably just think your fabricating something to make her break up with her BF.

You do or say nothing,as it's their business not yours. Sooner or later she will find out but coming from you now it would be a case of shooting the messenger.

If you obey one relationship rule, you'll forever be "good" in future dealings with love...

In a relationship = Off limits. Period.

If a girl/boy is in a relationship/engaged/married/or otherwise taken, she/he is off limits. Period.

I have to agree with the rest. The girl isn't available - she's already tken. Until she figures out that he's cheating on her and decides to dump him, my advice is for you to stay out of it.
