falling out of love

Becasue they don't understand the true love in fact.

I guess they just grew apart.If they married young and they grew a part. What they liked about their spouse then , they don't like now. Or they married because they were to have a baby and they wanted to do the right thing. But they weren't in love. So when the child or chilren are grown, they don't have anything in common anymore so they split up.

there are lots of reasons why couples falling out of love..like having cheating in a relationship, that if the husband is far away, the wife has has no trust to him because she thinks that his husband is looking another woman but sometimes it's true..also they don't have the patient in their relationship, specially when both parties are having that bad attitude and they cant swallow that anymore, so they quit and they end up in separation or divorced..

Relationships are like work to some extent. To achieve something we have to work hard for it. Feelings tend to wane after a while, even if there was strong chemistry at the beginning and even if the couple couldn't wait to see each other all the time at the beginning. So to maintain the marriage we need to be able to treat each other with respect, romance each other, put aside time to ensure that the other party continues to feel important, etc. All that will help in ensuring a marriage lasts a lifetime.

In love you can make mistakes, but the biggest mistakes you could ever do is to give up someone you love and say : it's for the best so we'll stop hurting each other..
