When you marry and make a serious commitment, then as a normal person, you will expect to have that commitment in place.
I guess it takes time to accept living alone, when everybody around you is married whether happily or not, but are married. When you are married, you may wish many times you may be alone and not dealing with conflicts, but other times you wish to have conflict, but not being alone.
It is a huge adjustment and it is very hard to swallow, when lonliness is emposed to you not wishing by you..
Relationship with repsect to blood, you know they love you no matter what, even many times your siblings or parents may say they don't, but seeing how fragile is marriage is heartbreaking, when your spouse says I am not in love with you, it is end of the world...
Marriage is relationship of love, you can have thousand firends, but you will love only one person, when that breaks, everything breaks, just pretending to be freind is a phony and unnatural. Yes it may feel great to tell OTHERS, oh we parted on a freidnly terms. Divorce is not a happy event, that we shake our hands and say good bye to each other. It is a sickness, which leaves life long wounds...
Yes we all learn to move on with our lives, but none of us ever forgets, somebody really has betrayed us and it does have an effect on us, which is trusting another one will be a hard thing.
