I think we have different personalities that just are unable to adapt to each other in a compatible way. In no way is it either of our faults, but I'm someone who needs more details, and you are someone who may know something right away if that makes sense. You also like to take your time on these kinds of things, while I would like to just jump straight to it and deal with the conflict right away. I expected too much of you. I believe my long-term one-sided romantic feelings for you may have enhanced those expectations, considering romance increases expectations overall in relationships compared to friendships, so I am sorry if my actions or behaviors may have lowered your standards or self-esteem, as I realize people have a bigger influence than they realize. I have tried extremely hard to keep our friendship peaceful as I could even at the cost of repressing my own needs. As I finally make more friends that I need, I realize I want friends who help me grow and are as socially extroverted as I am. I hung onto you because I had no one else literally. I am more than and extremely grateful to you but I just want my needs met and to try and find the people I need and not have to only rely on you. I also think we're at different growth levels and I struggle to adapt to change too.
I'm really, really sorry for dumping all of my pent up emotions on you. The truth is, I've been feeling that way for a long time, but I've been hesitant to express it because I didn't want to burden you. I know you have a lot of going on and a lot of stress in your life. I know I can't express it in a way that you may understand, but I am really grateful for all the things you've done for me despite knowing how much is on your plate. You don't have to keep pushing yourself for me if you're really stressed out. I just wanted to know that I am still loved and appreciated and that you're still here.
I have so much anxiety when it comes to you. I don't want things to end up like how it was with my previous relationships. I don't want to lose you. I don't want to lose what we have. For your information, my best friend who has a better understanding of how you process things has been helping me understand you better and to efficiently write this document in a way you can understand too.
