that cannot trust on you.
I am not saying that you have to give all you have to another person all at once, by all means go at it at your own pace, but you cannot expect someone to trust and respect you if you do not do the same in return. Lets face it, people are selfish. And the only way that we can work on fixing the lack of trust is to start to give it.
Any relationship (interaction between two people) requires a level of trust and respect. No matter what kind of day I am having I refrain from walking into a fast food restaurant and bitching out the person behind the counter, they play a role in making the food that I am going to be eating. If want to be able to trust that the person is not going to clear his throat into your hamburger, a small amount of respect is necessary.
If you think that your spouse is not respecting the sanctity of your marriage, it is time to seek professional help. Both for you singularly and as a couple. In the case of someone not respecting you, it is most likely that you have not trusted them.
Sometimes trusting another person is sitting down and discussing your concerns, if it gets to the point where you think they are having sex with a co-worker, chances are that you have not been completely open and honest. It is true that long lasting relationships can be built on lies, but healthy relationships are based on trust and honesty.
If it gets to the point where you are not sure of the answer to the question being asked of you, be honest and say that you do not know. If you are afraid that you will hurt them, tell them you do not know how to say it right. It is still being honest to say that there are things you are not ready to discuss, just know that there reaction deserves respect, as does yours, and compromises have to be made.
Trust and Respect are give and take, in order to trust someone you have to know that they trust you.
