Frustration

A lots of people are saying we are the perfect couple and the couple that would stay forever. That is what I wished and I believed. But in recent years, our marriage is like a rock on the edge of cliff. Any Small stuff can push that rock out of sight. I have been trying to comprise our conflicts/disagreement, and avoid fight , especially in front of Thomas. But his mood is just like a roller coaster. You don't know what you expect. His temper is getting worse. I've been trying to protect Thomas whenever he is in bad mood, but it seems he is doing it intentionally. I've been very patient and tolerant with his behavior. Thomas is such a sensitive boy and I can not stand to see him get hurt. One time I promised to God - I would never fight with him in front of Thomas. But he knows my 'weakness'. The more I keep patient and tolerant, the more he pushes. What happened last nigh really push me to the limit and made me think differently. This marriage would not do any good for Thomas. Irony all my friends around me think I am a good communicator, but i can not communicate with my own husband. All he done made me speechless and hopeless. I desperately asked God so many times to help me and give me strength and wisdom to hold on this marriage. I've been trying so hard, but marriage is not about one person , it's about two people. I am really tired. Maybe it's time to let it go...
