Marriage is never an achievement. Peace of mind is. Take your time to analyse the person you are with before commitment. They will determine your success and downfall. The biggest mistake you will ever do is on who you choose to marry.
Love this quote by @CJakesColeman "Loving someone is being vulnerable to give them (your whole heart with) the right to hurt you, hoping they don't."
To have honest, open, transparent communication may hurt sometimes but if it's done with love, wounds will heal&you'll grow.
Make a meaning out of your circumstance. You might not like what you’re going through right now, but there’s a reason why you’re experiencing it. What you’re doing now is all for a better tomorrow. So don’t give up just because you had a few tough days. Keep going my friend.
