Input: so first things first my girlfriend and I were in a relationship for 3 years March 1st.  Lets call her Bri. We tried taking a break a few weeks ago but in the end we decided to end things. One thing she was worried about was this girl from my past. We will call her Lea. Lea and I were really good friends and quite frankly I was really really into Lea back then, but she ended up moving away about 4 years ago. Lea recently moved back in town and things went wrong fast. My Gf (now ex) said one night I said her name in my sleep and she has been sulky ever since.  I told her Lea was not a problem and at the time she really wasn't. I explained that we were old friends and I even kept Lea at arms length to help reassure my Bri. Bri and I have try to keep things civil and remain friends but she has been aggressive and really snotty to me recently  amongst  our friends and in behind closed doors.  I have ultimately decided that our relationship can no longer last in any form including friends. Since Bri and I broke up and we are not really friends I have been hanging out with Lea a lot as of late. All my old feelings for her are flooding back in. In the back of my mine they have been there since she came back. Now I really want to try things with Lea. I didn't cheat and for the most part have been truthful and honest but I can't help but feel as if I am still in the wrong.

TLDR; AITA for wanting to pursue the girl I told my ex-gf not to worry about?
