You have to take a relationship seriously and make sure that you keep the lines of communication open. If you take your partner for granted, then you can expect the relationship to fail. If you shut down and don’t talk to your partner then you cannot expect it to work out. If you are too secretive and keep too much to yourself then it is easy to see why someone else would not want to be around you. You have to learn to open yourself up even if it is gradual. If a person hits a wall every time they try to get closer to you then they will give up quickly.
When you have a problem trusting people then you may have a hard time staying in a relationship. You have to let go of the past and begin to let people in again. If you cannot learn to trust again no matter what the reason, then you will always be alone. If you are sure that you would not trust someone enough to get involved then give yourself some more time. When you are ready for a relationship then you will be able to put your trust in someone. Rushing into something too soon is a number one reason that relationships fail.
Sometimes you can be your own worst enemy and allow fear of getting hurt keep you from getting involved seriously with someone. You also may be selfish and put yourself in front of your partner. It is important to find yourself before you can be truly happy with someone else. If you are still putting yourself first then you may want to wait to get involved or none of your relationships will work. Being selfish is not going to get your anywhere with your significant other.
