Bro, just let him go. It's his loss. I know it's going to be really hard on you like last time because you care and love him. But if he doesn't understand that and still wants to run away, just let him run until the end of time. At this point, you're the one getting hurt because you trust him and loved him with all your heart, just for him to run away when things get hard—to run away when his thoughts win. Why can't he choose you just as much as you choose him? This is not fair. Loving someone is so hard and draining to the point where you should just disappear, live your life, and let him run, because that's the only thing he'll ever do.
