I m writing a farewell letter to my friend who was my room mate for 3 years. Please correct my english.?

My Dear Roomie,

Four years of engineering and three years of you, have gone and we didn't realise. Well, by the time now, we are graduated. I don t have any creation to write, I would be simple.

Many a times, things have gone wrong between us and many a times I was the reason. I apologise for my mistakes, till now. But, I know, you remember, you are one of the few person, I really trust and I will.

Oh, one thing I forgot to tell you. You always told me there is only one thing you are fond of. Clothes. Its true my jeans was worn out, but I didn't take you to buy me a tee shirt. It was your birthday gift. What I didn't able to give you. Its there in the shelf.

Well, I know what you were looking for in the whole letter, my grammatical mistakes. Right? You wont change Er. Yogesh, our modern shakespeare.

You always say. Alls well that ends well. But its not an ending.

Will see you again. Soon.

Your Roommate
