Why is she doing this? can she be trusted?

she sounds like she wants to make you like her, and by doing this she wants you to be happy and forever in debt to her when you fall madly in love with the man that she found for you, but guess what, if you don't like him, then tell her and that will make her think twice before hooking you up with family, and yes that is sorta weird, just tell him you only want friendship and he will back off, but don't be cruel, because he probably really likes you...not his fault, blame your aunt, or whoever she is...
