You can’t blame divorce on anything else but selfishness. Anything can be worked out if both parties are willing to be giving to the other. If either party is too selfish to put the other’s needs on the same level as their own, then that is the party that causes the irreconcilable difference.
No one can interfere in a marriage if a spouse is not selfish enough to let their ego get the better of them, and put respecting their spouse first.
Friends can’t interfere in a marriage, if one’s spouse is more important than the friends.
Parents can’t interfere in a marriage, if one’s spouse has the top position in their priority list.
Nothing can interfere in the marriage if you keep your ego, your selfishness, and others in check.
