Someone summed it up about divorces with profound clarity and insight, he said.' The main cause of divorces is marriage'.
I really can'y argue with that,
I also can say "the main cause of abortion is intercourse"
It all depends on a lot of factors as to how a marriage work out. For me, I'll sum it as,
1. The efforts by both parties
2. Internal environment i.e. living conditions
3. External factors i.e. working environment
I count my blessings that my marriage is still going strong
