At one time or another we have all been burned. It could be tough entering a new relationship. How do we handle relationship failures?
Address all fears of relationships. Get to the root of the problem. If you have a fear of getting hurt try to let it go. Not every relationship will be like your past. Just because you were cheated on in the past does not mean that the person you are with now will cheat on you. Give the person you are in a relationship with and the relationship that you are in a chance.
Be compatible on all levels. You need a common ground when entering a new relationship. Make sure you get along; physically, mentally, and emotionally. Have some things in common. Make sure that you are both giving equally and that one person isn't giving more than the other.
Love yourself. Don't allow yourself to be mistreated. If someone is treating you wrong and you know you should not be with the person than split. The more you stay in a loveless and wrong relationship the worse it gets.
Before entering a new relationship make sure you have all of these factors. If you need to talk to someone then do it. The worst thing you could do is jump into a new relationship thinking it will heal you. If your past relationship keeps occurring and running your present relationship then there are some things that you need to work on. Don't let a past relationship ruin your present and future. Each relationship is different and every relationship is a lesson in what to do better in your next relationship.
