Rate my breakup text?

I recently posted about when to end things with someone and I think it's time for me.

Interested in feedback on the message I plan to send after the work day today. It's long and I don't really plan to shorten it, to be honest.

"Hi! I'm sorry I haven't been as responsive today. I so enjoy your daily texts but I'm feeling that you're lacking genuine interest in really engaging deeply with me in between seeing each other, and lacking initiative on making plans to see me again. It leaves me wondering where I stand in your mind.

I've been happy with our time together and getting to know each other better and I have taken a lot of initiative to make that happen but I'm looking for a dating partner who actively wants to spend time with me on a regular basis and takes initiative to do so, allowing us to engage on a deeper level to see what a more intimate connection might produce.

It seems that it might be best to pursue our other connections where there's more alignment on these couple of things. What are your thoughts?"
