I wanted to write to you....

Sometimes I remember [or use reminisce, it means the same thing but it is more romantic, if you use reminisce you would write "reminisce about the times we talked"] when we talked for long times... ["long times" may not fit gramatically...you could replace with talked for hours/at length]....I never told you but it was really interesting for/to me. I loved when you told me about your day or what happened with you. That/The day when you said to me that you were beginning to love me, I could not completely understand [you could write 'or respond in the way I would have wished] but I felt a lot of things because you liked me. I felt in my body many feelings/emotions I had very much time that not feel like that I had never previously felt that but I really loved it... I do/did [keep it in the past tense] not know why I could not express how I felt about you?? and I hated that because I did not know or what was happening with me. I could not control me myself [you could replace the above with: "I hated not being in control of what was happening to me or what I was feeling"] I just felt... you just made me feel [not sure if you wanted to use a word after feel?] So now...? Now? Now all is really everything is different [or everything has changed]. We have took taken differents ways paths, and his your way our paths may never cross again. In some moment I thought [You could write: At times, I thought/hoped that we would get second chance that may, just may our ways will find in any case but I was wrong. Sometimes I want to cry because I never thought that this was going one to end this way. I never thought in this this would happen... I just lived in the moment, I just lived him the idea of being with you...
Now I can see that I was wrong, I was really wrong... I cannot doing nothing anything because there is not is nothing I can do. So, I just miss him you. [I've changed him to you because you want to keep the same tense]. 

Great job Nicole! This is a beautiful [and quite sad] post and really well written. Your English is great. I've just made a few suggestions. Sorry, my edits might be a little confusing.

Thanks for sharing it and I wish you all the best! Elias.
