I met someone while on a “break” with my boyfriend

I’m 19, both of the other people mentioned are 18.

My boyfriend and i have been dating off and on for over two years. He’s broken up with me two times because of wanting to meet up with other girls and using his depression to hide it. He begged for me back a third time, so I told him this would be his last chance to actually change.

He did change for a while, like a month or two, before he went back to deleting messages and repeating the same behavior. I was getting seriously depressed over it and my attitude towards life, and him, changed visibly. I wasn’t happy. He asked me why I didn’t love him anymore, so I explained I’ve just been depressed because of what’s been going on.

He immediately became angry and said me being depressed made him feel like he wasn’t a good boyfriend. I apologized and told him I loved him, but again, he wasn’t sure about me anymore. He wanted a “break” where we aren’t together but still talk to each other.

At work, I met someone near my age as well. He’s really funny and we got along really great, but drifted once he learned I had a relationship. I also drifted willingly, because my feelings for him weren’t exactly platonic anymore. But now that my boyfriend has done this, I’ve realized how much I like this person. I’m not sure what to do.
