How do i resolve this issue with my friend?

Maryam sounds like a nice person, but she also doesn't sound like a true friend. I wouldn't just ditch my best friend for someone else i met. I think its worth the try though, maybe send her a facebook message telling her you miss her and it would be nice to get a cup of coffee together. If she doesn't reply then you know for sure she's not worth it. but if she does, a friend is always better than an enemy :)
