Watch over your heart with all diligence, for from it flow the springs of life. Proverbs 4:23
There is no big secret to marriages, it just takes two people who are mature enough to find ways to work through their issues. The problems arise when one or both of the people in the marriage are unable to work out their issues in a constructive way.
What can you do to make your relationship better? Well, that depends on a lot of factors and since I don't know you or know anything about your relationship, all I can do is offer you some generic ideas to improve your relationship.
1. Do not tolerate dishonesty.
There is no excuse for someone to lie. If you are with someone who lies to you all the time, you have to ask yourself why in the world would you consider continuing a relationship with someone like that? It just does not make any sense.
2. Do you and your husband have difficulty talking over the issues that come up in your marriage?
The longer the two of you are together the more difficulties you will face. If you are with someone who isn't going to have your back, I have to ask again: why would you stay with them? It just does not make any sense.
3. Do you know how to let your husband know how you are feeling in a good way (which means you don't scream, cry or act like you're 12)?
If not take some time to learn how. Does your husband know how to express his feelings in a good way? If not, do you think he would be willing to learn?
4. Do you and your husband have good problem solving skills?
Knowing how to deal with problems is a great skill to have in all aspects of life, not just relationships. If you are a good problem solver but your partner is not, it will only cause friction since you will have to carry much more of the load. This skill can be taught so if either of you aren't good at problem solving you may be able to get some help... if you're both willing to invest the time.
It frustrates me so much when I hear my friends talk about the issues in their marriages. They want to know what the secret to marriages is, you try to point out that the husband isn't a nice guy.
