<human>: Can you provide a brief overview of the text?

Almost a year ago a met my ex. He was about 3 months out of a bad breakup and pretty emotionally damaged. We were friends for about 4 months when we started dating. I was skeptical since I wasn't sure if he was emotionally ready, but he promised he would try his best.

After dating for 5 months he broke up with me because he wasn't as emotionally ready as he thought he was. We decided to be friends because he still liked me a lot and we both considered each other to be each other's best friends. I chose not be as close since I was the only one to say, "I love you" in our relationship and I felt that I was more hurt coming out of the relationship. Since we weren't as close I didn't realize he was getting close with another girl. A month after we broke up he started dating this other girl and I feel like I'm heart broken again. He still wants to be friends, and I still want to be friends because he is one of my best friends. I'm just not sure if it would be best. What would be the best thing to do?
<bot>: ! My ex and were friends after our breakup. He is dating another  girl after a month. Should I be friends if I"m heart broken all over again?
