Relationships are supposed to be able to bring out the best in us but many times it is the root for needing self help advice. Most self esteem issues are directly tied to relationships we are in. It doesn't matter if you are dating or in a marriage or just in love, it can either make us feel better or worse about ourselves. We strive to find the one who will love us and make us feel like we are on top of the world, unfortunately that doesn't always happen.
One thing that many will try to do is find out if the reason for your difficulties in your relationships is because of the problems between the two of you or is it because of problems that originated early on in either your life or the other persons life. It can be exhausting trying to find the original root of the matter but one thing is obvious, you have problems now.
The best thing to do is to try and fix the relationship that you are in now so that you and your spouse or partner can help overcome each other challenges. You may be interested in reading self help books and utilize different self help techniques. If your relationship is strong, though, there will be no more need to concentrate on healing yourself because you will have a partner to help you overcome. First, though, you need to work on building the relationship. Seek out some good marriage counselors or others who can give good relationship advice.
One thing that is going to help is to never allow yourself to be criticized, or at least don't internalize it. Also make sure you don't criticize the one you love. There is no such thing as constructive criticism. There is nothing constructive about it. All it does is make one feel less powerful than the other and it is used to manipulate much in the same way an abuser does. A relationship is not a power struggle and it is not a war. Quit treating it like that and there won't be any fights to win or lose.
There are some more things that you can do to help your relationship. Where you are separated by beliefs, try talking it out and instead of pointing out where each other is wrong or where their weaknesses are try to find common ground. Take time to discuss what each other's roles are in the relationship. Also discuss what you expect of the other. Let your partner know what hurts but also let them know what it is you want or need them to do and try to offer the same to them.
Whether you are dating or involved in a marriage there are many things that you can do to help better the situation. Once the two of you have worked to repair the relationship and put away any talks of divorce, separation, or just breaking up, the two of you can work together to make each other better people. Your relationship will help you help yourself image and will help you overcome all those things that hold you back.
