My first wife was a wonderful person and a good wife. She did not do anything wrong other than work to much and trust me. If that makes any sense. She would work all day and stay at her parents home on the weekends because she had to be up early in the morning to go back to work. It saved her a lot of time on the commute and give her a couple of hours of extra sleep.
So like a good husband I started to go out with some of my friends on the weekends without my wife. My intentions were never to go out and find a one night special, but it did happen a couple of times. Next thing you know I had a girlfriend and I could make dates on the weekends because my wife was not around. She trusted me to do the right thing while she was out making money for our household. Well as you can see I was not doing the right thing for our marriage and we grew apart.
She put money in her first priority and I put a good time in my first priority. She made a lot of money and I had a lot of great times without her. The reason I say this because I was not in love with her my wife anymore, she became a habit. I cared for her, I loved her, but I was not in love with her like when we began. We were not the happy couple anymore on the inside and it was troubling and I suppressed it with the good times on the weekends without my wife around. She was a habit that was hard to change because I was to worried about hurting her and telling her that I did not want to be her husband anymore.
When we did split it was a very sad time for both of us. I will never forget one thing she said to me, "name, I am not the same anymore name, a part of me has died!" It was the truth. A part of both of us did die together that day.
But the good news is that life is full of new beginnings and delightful surprises. The point I am driving home here is that is if you are not happy with your spouse (or friend) consider changing your priorities and goals. If you can not make your loved one a #1 priority I think you should reconsider your relationship and decide if any changes are necessary. I know a relationship can become mundane, but if it is just boring you should give it a spark and reconnect.
