They say that a lot can happen in a year. You meet new people every day, and relationships either tend to rise or fall depending on the situation. People can grow or shrink, depending on what causes them to do so. Change is always the biggest problem or solution in any friendship or relationship. Some change for the better, such as some partners can make their significant other into a much better person. But then again, some significant others can absolutely bring you down and make you into the shell of a human that you once were.
I have a best friend who became affected by that, and totally changed who they were. They were always with their significant other, never went out anymore, and would never stop talking about their love life. What I miss is the person I had access to every hour of every day. I miss the person who would be free to see me most days of the week instead of revolving their life around their partner. I felt like the friendship we built was slowly becoming washed away by your new relationship. If I were to write an anonymous letter to you, I'd pray you would have a feeling it would be from me.
You, my best friend have changed drastically. You're more touchy, more sensitive over what I and others say. You were never like that before, you went with the flow and made fun out of every situation, good or bad. But lately, every time something affects you, you break and blame it on everyone but yourself. I looked at your Instagram the other day, you claim to be so happy now, but that's something I just don't see. Last year you were living and thriving, and there was a smile on your face almost every second. Nowadays, you look more tired and hidden, like you don't want to announce what's really going on. You're distant but I see what goes on between you two behind closed doors. You're controlled and then talked down to, and that is not okay. I can't be in your relationship with you, but I can sure tell you my opinion.
I saw you change the second it became official, I knew things were going to become different but I didn't think they'd be as low and distant as this. I feel like if I haven't lost you, then I am just starting to. You changed from a bright, social butterfly into someone whose antisocial and refuses to look at another human being that isn't their lover. I miss that fun girl who I'd have a ridiculous time with, I just wish she could find her way back without being unhappy. A relationship is hard work, but it's important to not make your relationship your entire life.
