Emotionally Destroyed

The day started out good because I had a boyfriend who I thought loved me as much as I loved him. We had just started dating on September 25th and I had a boyfriend that I dumped just to be with this other guy because he made me so happy. That day ended great because I just got a guy who I thought liked me until September 27th. On that day I found out that he said he felt like he was being forced into a relationship. I thought once he said that he was still in love with his ex girlfriend(aka my best friend).I thought that because she let me go through her text and he said that he hopes he will marry her and that's when I wanted to kill myself right as I saw that text. I really wish that as a best friend she would have at least told me that she really did still love him. If she told me that I would've never said yes and tried to get them back together. We are all still friends, but I'm still just disappointed,sad,mad and kinda heart broken.
