Hello there lil.lily
Well to be honest , I have always lived by forgiving and not forgetting I believe though you should forgive for your own sake and move on you should not forget what they have done and let them do it to you again. But my question is , is that if he has hurt you so much why do you still talk to him? I would advise you to stay away from people who try to hurt you and not really think about them and their lives. You can’t decide how karma gets to them and when, and you can’t decide how they live their lives, but usually people who don’t care about hurting others tend to focus only on themselves and thats why he’s “happy” which is probably something you should start doing (focusing on yourself, not hurting others) The best thing to do is let him go completely don’t worry about what he’s doing or how his life is going you don’t need that kind of negativity around you, just focus on making your life the BEST it can be , after all life is what you make of it.
PS: Just because he is going to Hawaii doesn’t mean that he’ll have a great life , you never know whats really going on because people only share what they want to with you 🙂
