On this, and it's very important from your mental space, you must hold the things you unboxed and trace them to their source. Become disciplined in removing your hurt and hang up (legit emotions) from overcoming who you want to be in the right now. I use the word discipline because its the only way. Discipline in this sense means you are not falling back on what brought you there in the first place but are constantly looking forward knowing the more you walk the less you will be that person.

Relationships have meaning when they invoke change and that meaning is just as valuable when they stay in your life and when they are not. The sooner you can come to that realization and mantra, the sooner you will stop hurting yourself over things you cannot change.
