I'm 24, i've been with my current girlfriend for 5 years (shes 23). We both know this girl, lets call her Ashley, who hangs out with us occasionally, weve been friends with her since high school. Ashley and I don't have a history, she has pretty obviously flirted with me before though, she tends to flirt with a lot of guys. Recently though she has been giving me weird " shit tests" I guess you could call them.

She basically calls me out for not being a good boyfriend, even though I am, and even though my girlfriend is very happy with me. For example, we were at a party last night , and my girlfriend wanted to leave around 1, as she was tired. I was ready to go until Ashley said "yea, come on, your girlfriends tired you need to take her home", to which I responded "i'm talking to my friends." and resumed a conversation with one of my buddies.

Another example, she always does this weird thing where if the three of us are talking she'll tap my girlfriends cheek and say "kiss her!" - I don't need someone to tell me what to do to my own girlfriend lol. Also, whenever my girlfriend mentions a restaurant or something she wants to go to Ashley says something along the lines of "come on man! take her there!" and if I ask about the prices Ashley will say something along the lines of "your definitely paying right" to which I say that as a strong supporter of equal rights, I wouldn't think of paying any more than half.

My question is, why would she seemingly have such an interest in how good of a boyfriend I am, or how the relationship is going? Its annoying me and my girlfriend. The whole things just weird and I need help making sense of it.
