The man I love is marrying someone else

I don't really like to talk to my friends about my boy issues because I don't want them to defend me and attack him when he doesn't deserve it, but I just want to kind of shout into the void just how much it sucks. We've had kind of a complicated history. It's like fate had other plans for us. And now he's planning on marrying someone else, and though I saw it coming, it's still kind of hard to breathe. I know it'll end up being okay and I'll (hopefully) get over it someday, but someday feels so far away right now
