Am I overreacting to my boyfriend (again)?

I'm back with another issue that arose just today. I've been asking my boyfriend for one simple favor: to text me when he leaves and when he gets home so that I know he's safe. I have his location, but I’d prefer a text. It’s frustrating to wait for a reply only to see on his location that he’s been home for 20 minutes without sending a single message. I called him and reiterated my request, explaining that even if he's busy, a quick text letting me know would mean a lot. It's a small gesture of care for someone you love. He agreed to try, but then because I expressed my lack of trust, we ended up discussing how I feel when he doesn't follow through on his promises to step up. It makes me feel frustrated, especially since I'm trying to improve our relationship dynamic. He brought up that he feels like he's been trying to change me for over six months, and he believes I only start to improve when he pulls away. He said he’s no longer willing to make any changes. I know I wasn’t my best self back then. I was struggling to improve and often ended up going in circles. Only recently have I started to understand my past behaviors and how to communicate better. Hearing him say that because of my past, he won't change for me anymore really hurt. He ended the call, unwilling to engage in the tough conversations we need to have. Now, I'm feeling lost. I don’t want to lose him, but if he's not open to making changes, I'm not sure where to turn next.
