<human>: Can you condense the text into three sentences or less?

So. My ex boyfriend left me 2 weeks ago for a girl he cheated on me with. I'm still hurt by what he did but, at the same time, things between he and I sucked anyway, so this break up was for the best. I'm trying to move on now. 

After the break up, I called up a mutual friend I had with my ex. I had always felt like we connected and so I vented my feelings about the break up to her. I mean, I was really relying on her support, we talked for hours at a time and texted. She seemed to really understand what I was going through. 

I don't know why I did it, but the other day, I was Facebook stalking my ex and his new girlfriend. I noticed this mutual friend of ours has befriended this girl, "likes" all their cutesy posts and pictures, says what a cute couple they are, and she's even invited them over to her house. I know she had been gossiping about what we talked about because my ex's new girlfriend wrote some snarky remark about people not knowing when to give up, blah,  blah. My "friend" wrote her something about not letting jealous people ruin your shine.
<bot>: I'm just looking for some support here. I feel betrayed by my cheating ex boyfriend (who I was with for 3 years, he left me high and dry) and this backstabbing friend.
