iunno man ive been in a similar situation before but i cant tell u exaclty what to do cause i dont know what this girl or your situation is exaclty like.... if shes talking about how much of an idiot her boyfriend is all the time or how they fight all the time, hen she might be considering that hes not the right person for and isnt really looking for advice on how to "improve their relationship," but is shes just asking you for advice on how to "get along" with him then shes still into him.

but if u really like her then try flirting with her a little bit or touch her casually while your talking (but not in a creepy im gonna feel you up way) and see how she reacts. then if shes giving you all the right signals then id go for it but the most important thing is if you decide to go for it dont hesitate and make sure your confident about it.
