Contrary to general belief that marriage is a walk in the park. Well am sorry to disappoint you, it is not. We fight, we disagree, we argue. But in the midst of all these, we compromise, we communicate (No pending issues). That's the beauty of it. That doesn't make us less of a good husband or a good wife.

If anyone tells you that his or her marriage is perfect and rancour free, the person is a liar not from earth but from the pit of hell.
Deal with pride, arrogance, individual glory (In marriage it is WE and not I), selfishness, prayerlessness, laziness (especially as a man), cunningness etc marital crisis will be 99.9% avoidable. Quote me anywhere! Many marital crises are behavioural.

Just like coach Joshua said in one of his mentorship mail "marriage is as simple as ABC but most times our complicated personalities make it complex".
Working on yourself before walking down the aisle is a wise thing to do.
This is a fact, not a fallacy.
You know I love you. Stay safe for me please.
A more impactful and responsible relationship is possible.
