Alright,

so my friend recently introduced a girl into my friend group, who are mostly guys. I recently broke up from a bad relationship and became attracted to this girl very quickly because she is very chill to be around and I am probably desperate. I don't know her that well and know that I am indulging in most of my insecurities here, so much of my feelings are based on irrational thoughts. 

I get these flare ups of jealousy, mostly minor, when she is interacting with other people in my friend group but not me. I am able to push these feelings to the side mostly but they tend to come up every now and again. I am by no means mean are possessive outwardly towards my friends and I like them, but when this girl is interacting with my other friends and not me, I get this twinge of jealousy even though she has interacted with me before. Its like I have to automatic possessive desire to have her to myself and have her only interact with me, but I resist it because I know its bullshit and she is her own person and wants to be friends with all of us, not me.

 The idea of getting into a relationship with her actually concerns me because I am afraid the insecure habits and emotions that developed in my last relationship would affect any potential (and extremely unlikely) relationship with her as I would just become a total dick. 

AITA for even having these feelings? I push them to the side most of the time but I am sure they are unconsciously affecting my behavior to be more possessive in my mind. To clarify, this is all mild in my mind and I do not make it a problem for my friend group in any way, and I have not outright told anyone in the friend group of my attraction. Also, I am getting no signs from her that she is interested and consciously think it is ridiculous that I would be attracted to her this quickly. My thoughts and desires are igniting primal possessiveness in me.
