Confused about my ex and a friend's confession

Your emotions are valid. If you think you need time to heal, then you need time to heal. You shouldn't think about what you should do, but rather what you want to do. I think vocalizing your concerns with both your ex and your friend would also be beneficial in regards to closure. It seems that they are both unintentionally crossing some boundaries or maybe you are crossing boundaries, which you have to acknowledge. I wish the best of luck to you and I'm open to talk if you need someone

You have a right to feel the way that you do. I personally do not believe in being friends with "ex's" because of the emotional feelings that may resurface. You should tell your good friend that you don't feel the same way, but would like a friendship with him. I'm here to talk if you need as well.
