Wait a minute so part of why you want to break up is because he is reserved? But you’ve been talking to and catching feelings for another man that you plan to leave him for. … if that’s truly how things are then for both of your sakes break up. You’ve already shown you can move on at this point you need to think of him and the best way to let him down easy. I understand not wanting to tell go but you’ve clearly done so a while ago. And the guy your with sounds like a great guy just not your soulmate he deserves a change to move on and find love again as well.
