1. It’s really wrong that you denied it, and that you even did it at all. A relationship is built on communication and trust, and you really shouldn’t mess with that if it can be avoided. But the past is the past, and you can’t change what you’ve done. You can only try your best to turn your wrongs into rights. Honestly, if you are still thinking about a mistake you made a year ago, do you think you could keep holding it inside? I think you do want to tell him, and that’s why you haven’t let go of it.
2. Of course it will be! It’s completely understandable to be scared in a situation like this, but I know you can get through it. You just have to be strong. :)
3. I think you should talk to him yourself. Maybe he didn’t reply with something more because he doesn’t want to talk to your friend, he wants to talk to you. And honestly, if you want something to happen, you have to make it happen. Don’t sit around and wait for him to make the first move.
