The best lesson I ever learnt is that life goes on. People come and go, we lose friends, break up with lovers, meet new people, experience success and failure and life goes on. You’ll be alright.
Y'all call it cuck babble but I honestly believe that a lot of men need to come to terms with the fact that their women can and will cheat if they want to. Rejecting this leads to them reacting violently when another man proves it true.
Whatever you do, pray for the ability to see your own sins, your own hypocrisy, and your own shortcomings. Never get so carried away pointing fingers that you forget you, too, fall short.
