Before and after marriage
Based on observations one of the main reasons some of the love marriages ends up in divorce is because of the change in expectations which can be summed up in 2 lines.
Before marriage : I love you for who you are.
After marriage : I will love you only if you are the way I want you to be.
If you are considering divorce, think over, has your expectation changed? Maybe in that case the problem is with you.
