Oh love, I'm sorry you are going through a hard time. I'm sorry the heartbreak is hard, but at least he's being honest with you, and you have this little group to send you encouragement.
I've been loving reading in the background as your duck feet journey has unfolded. I don't know much about ducks, but it's heartwarming none the less. Grief and sadness are not emotions to shun. Take time to go through these emotions. Maybe do some introspection and quiet thinking. Take care of yourself. Eat well, go walk, drink water, sleep regularly. Even if it doesn't work out, it sounds like you two have had two good years of memories and experiences that have helped you grow, and this in itself is a blessing to remember. I hope things work out for the best, whatever that may be.
