Tough situation, I'm sorry you feel this way. It's good that you were honest. I think the only thing to do is move on from this, even if it seems impossible. Start a new chapter, with or without him is up to you. He has forgiven you and that's his choice. You can't change the past, right? So take the time you have now and better yourself. We all only have such a short amount of time, it's impossible not to make mistakes and you've acknowleged that you made a mistake. That's great. So you can actively work towards not being that person again, time changes everything. Stay strong
