This all started when my first gf ever broke up with me, this of course left me in a state of severe depression for several weeks, so my best friend seeing me like this, invites me to a party so he wouldn't go alone.

He convinced me to go and there I met some really cool people and in particular I met the girl who had invited him to the party in first place and we kicked it off from the start, dancing and singing to every song and at the end we exchanged numbers so everything was going well for me until my best friend (I'm gonna call him bestie from here on out) tells me he's had her eye on her from a year ago so I backed off and started talking just as friends with this girl.

Couple of months pass, and bestie tells me he needed help with how he was going to ask her to be his gf so I helped him get everything he needed, set up the place and make sure everything went smoothly. During this time I've made a place in this girl's heart and became really close with her but keeping boundaries for I thought my bestie was right for her. 

So everything went well with their relationship, until they started fighting for everything and I cannot stress this enough, EVERYTHING was a good reason to fight, and me being in the middle of the trouble I had to help bestie and his gf get everything back to normal so I helped her whenever she cried for him and encouraged him to write back, this went on and the relationship was getting nowhere, she was crying almost every day and it broke my heart and he was starting to see other people even though they were still on a relationship, so she found out sooner than later and broke up with him.

This was for the better since I haven't seen her this happy in months, we text everyday and I encourage her to go out and experience more, to be happy with other people, but this makes my bestie mad since it's not in the "Bro's Code" to talk to your best friend's ex, and we've had very bad arguments during this past week for this very subject. So AITA?
