It's okay to be sad about something you thought you had healed from because you are just human being and you are not perfect so not everything that happens in your life could be healed sometimes all things you can do for it is.
You are forgiving and take it as a lesson from what has happened and I assure you can continue your life with just fine, and just try to always be better than you are before and enjoyed what you already had now.
And also, you needed to be honest in yourself and never lie to yourself and also, I you are having a partner you need to be honest with them too about everything and don't keep anything from them because they are deserving to know about you.
Because if they didn't know about you at all how they can fully love you and want to be with you, and do not need to worry about what happened after you tell them everything about you if they really love you and they want you in their life's they will loves you no matter what had happened because they are loves you the way you are.
