For a RELATIONSHIP to really work, you gotta understand this: You and your partner are TWO different people, with two different pasts, trying to build ONE future. You didn't grow up the same, you won't always think the same, and that's okay. What matters is HOW you handle it. Communicate without turning everything into an argument. Listen even when you're frustrated. Stop keeping score and start choosing growth. Because every disagreement shouldn't create distance. It should build understanding
You CANNOT go back in time and change the decisions you took. Forgive yourself, move on, be your best version. You're alive and until death all defeat is psychological.
Rebuild.
