**Absolutely they can enter a new relationship and be committed to the new person wholeheartedly but as for the leaving the past behind completely, I don’t think thats probable. You are who you are and you’re defined by events that took place in your past. You can beat all odds to get what you want but you never forget who you are and the lesson you learned along the way. That is your past. If someone had a drug addiction, they are always prone to it.
Your past is alway following you. Its only a matter of accepting it.**
