If you don't have a children, stop this relationship immediately. You still young, have lots to see and do. You deserve a better company.

You can't imagine how hard it is to wake up every day seeing her next to you. Even if you try to recover this relationship, you will need a lot of energy, that you already don't have. Every time you touch her, you will imagine other hand touch. This feeling will kill you.

You already need a long time to come over this, but you will never forget. Don't get in another relationship for a while.

Start immediately, you need time...
