Please forgive me

Dearie,
I'm really sorry for what I did today. I know it caused a scar, and a visible scar. A scar that will remind us everyday of what happened today. I'm sorry I couldnt control my temper. I'm sorry that I hurt you so deep. I know you are heartbroken, and I know no matter what I say now, it will not heal the scar.
I promise you that I will not flare up like today. I promise I will try to control my temper. I promise that I will not be so rash anymore. I promise to be your good gf, and your good wife in future. I will put you before myself. I will not neglect your feelings. But at the same time, can you also try to understand our predicament? Try to understand where I'm coming from? And also try to be a bit less stubborn?
We both want to be together, till we are old and greying right? So can we please work hard together at our rs? Everytime we get angry, lets just calm down, not provoke each other further, but work things out together peacefully.
Can we not let our EE go to waste? Let's remember it well, remember what was taught, remember what we should do to maintain our rs well.
I love you dearie, and I know I've caused you so much disappointment and hurt. And today, I did not expect to be capable of doing such a thing. I'm very sorry, and I cannot forgive myself.
So to make things up, I will thrive to make things better in future. I know that we both are jumpy, becoz we both want a perfect home and wedding, but under so many constraints. Let us be understanding to each other, and set the perfect home for you and I.
Please forgive me.
