Letter for my ex-girlfriend. What should I do?

[Baffled_Bob]

Hello, I need a someones perspective about what I am trying to write to my ex girlfriend. I want it to really open her eyes and to see a different person in me. We have dated for almost up to a year and its been 3 weeks since I have talked to her and I was thinking a good time to send it to her is when I return her stuff. Does that send a mixed message if I send this letter with her stuff? Please do help me out. This is my one shot to showing her a different side of me. Thank you for reading.

>> Forgive me for writing you so soon. I have, however, come to some very important realizations and would like to share with you. I write this letter to you without agenda, but hope that there may be something I can still do before it is too late.
I know you are surprised to see this letter and I don’t think there’s anything I can say here that I haven’t said to you already--but I’d like to say more in a more articulate manner without the tension of our phone call, with the hope that I might reiterate how truly sorry I am and how I am willing to change because I have been missing you a lot.
I let my fears of losing you to ruin our friendship, our bond, and the best relationship I ever had. I have been thinking a lot about what I've done and how I have acted towards you and I was extremely immature. I want to apologize to you in a hand written letter, because it is the closest thing I can think of other than doing it in person.
I am sorry for the yelling and the fights. I screwed up, and misinterpreted our banter but wanted you to know that bringing unhappy feelings into your life is literally the opposite of what I wanted to do for you-and people's feeling are very important to me. Sometimes I assume too much. I see a strong woman and I forget that emotions are more delicate, and I'll feel bad if I knew I upset you.
This is no excuse, but please understand that I am trying to improve on what bad qualities and habits I have, which were hurting you. I think you are the best girl for me, and I am certainly blessed with your company. For the mistakes I have done, I am learning it the hard way. All of it has taught me about my mistakes, and what it would take for me, to be the best man in your life. And how I sit, realizing that I have to change my bad habits, I have been working on my habits of video games, grumpiness, sarcastic “jokes”, and neediness. I really want to do something to change the whole situation that brought us apart.
But instead of telling you that I will change, I have already taken actions of changing for the best. I have already stopped playing video games for 2 weeks now and mailed all of my video games to my 10-year-old cousin in Alaska. As for my grumpy attitude, I started working out twice a day to release all of my negativity. I have taken actions stop being sarcastic by getting away from my apartment as much as I can because that’s where it comes from and it’s a bad surrounding if I am trying change for the better. And for the neediness, though never planned on being like that, I have taken plenty of actions of keeping myself occupied with working out, going out, and slowing things down. I know this might take you a while to see this but I don’t want you seeing my same behaviors occurring over and over again like before.
You have always been very honest, independent, and have great pride and determination in what you set your mind towards, especially with applying to the Peace Corps, hard work with AXO, taking care of Finn, and education. I admire those qualities in you so much. I understand your reason for not wanting to be with me. You want to be the best "you" can be and focus on your college experiences, and I respect that.
Maybe after you have had some time away from me, you will want to talk to me again. Feel free to take your time and think on this, but understand that everything I have said is my true and honest feelings. You mean a lot to me, and I just cannot afford to lose you. Again, you can talk to me whenever you think is the correct time, but until then, take care of yourself.

Love,

I was thinking of adding more to the last paragraph but no good ideas are popping up. What should I do in general to add to the letter?

Did you really have to go post this in every single section!!!!!!!!!

i would spend more time on how shes special to you and less on how much you ****ed up... and try to make it so you dont sound so desperate.. you dont need to PROVE how you changed.. just do it... i would talk to her in person and not send a letter... meet up with her and bring the letter with you.. talk to her and then tell her you will give her what you wrote...

Again, its a nice letter but it stinks of desperation.. nothign wrong with telling her how shes important too you, but you cant make it seem like youll die without her.. make sense?

You can say somthing like "im ok being single, but I want to experience life with you." something like that... im not gonna write it for you but ill give you advice as best I can.

SHow her and tell her how she is special, but do it with confidence.... same point different way of approaching it with a better chance of success.
