Input: My girlfriend and I have been together for 1 year, but lately we've been drifting apart.

We have a long distance relationship, since she moved away from where I live about 2 months ago.

Everything was still going good for us, until about 2 weeks ago, she would text back later and later, and become a lot more secretive, to the point where I became suspicious.

My girlfriend and her best friend have been close for a long time, and while my girlfriend has been gone, me and her best friend have gotten closer.

Her best friend and I have a lot more in common than my gf and I, and she treats me better than my girlfriend. So yes, I started to like her.

A few days ago, her best friend admitted to me she had feelings for me as well, so I told her the truth about how I felt about her.

It turns out my suspicions were right. My girlfriend texted me admitting, she cheated on me. I told her I forgive her, but I really didn't.

...WIBTA for breaking up with her?
