Certainly! Here’s a polished version of your message:
"Hey, I hope you don't find this too strange, but I’m genuinely concerned about our friendship. Initially, I thought it was normal for relationships to take some time to develop, especially after 6 or 7 months, as long as there’s loyalty involved. However, I can’t help but wonder if I’ve done something wrong. I’ve noticed that I'm usually the one who initiates our conversations, and I'm starting to feel like there might be a one-sided effort. Is there anything that I might have done to upset you?"
Feel free to adjust any part of it to better match your style!
