It's tough to navigate these feelings, and it’s great that you want to express your thoughts clearly. Here’s a suggestion for your breakup message:
Hey [Her Name],
I hope you're doing well. I’ve been doing a lot of thinking about our relationship, and I feel like I need to communicate how I've been feeling.
Lately, it seems like there’s been a growing distance between us. I've noticed that when I send you a message on Discord, you often go offline without responding, and I find myself waiting hours for a reply on Snapchat. I’ve even timed it a few times, and it’s been over 8 hours waiting just for a small response. It genuinely hurts when it feels like I’m the only one putting in the effort to communicate.
Relationships require effort from both sides, and I’m starting to feel like that’s not happening here. I want to be honest with you—this situation is really affecting me, and I don’t think I can continue like this.
If you’re open to it, I’d like to transition to being just friends. I think it’s best if we stop seeing each other as we were.
Take care, and I wish you the best.
Feel free to adjust any part to make it sound more like you. Good luck, and take care of yourself.
