Heartbreak

I’m 21 and my ex boyfriend is 25 and we had been having some issues over the last 3 months of our relationship. I got diagnosed with depression and anxiety and he basically broke up with me because he said he can’t handle it and that “a relationship is about 2 whole people coming together to grow, not one person completing the other.” He said it’s best if we aren’t together right not but maybe sometime down the line, after we work on our emotional issues (my sister describes him as emotionally unavailable), we can maybe try again.

This is the second time this boy has broken my heart, but this is my first real heartbreak from a relationship. I don’t even know how to go about it. He always talked about us getting married and living together next year and he just dumped me randomly by text. I agree I need to find myself and love myself more before I can be in a relationship, but I love him so much and I’m afraid he will move on without even thinking about me. He just broke up with me 2 days ago and we haven’t really talked, does he miss me? I’m just so upset he seems like he doesn’t care.

I just need some advice on how to cope with the heartbreak
