Apology Letters to Girlfriend.
Falling Asleep Without Telling You

I'm sorry I fell asleep without telling you. I know I left you hanging and that's disrespectful to your time and feelings. You deserved to know I was going to rest instead of wondering if I was ignoring you or had forgotten. I take full responsibility for not sending a quick message or giving you a heads-up. That was my mistake. Even if it wasn't deliberate, my not telling you made you feel unimportant and possibly worried, and I'm truly sorry for that. I could have handled it better and I should have. To make sure this doesn't happen again, I'll keep my phone within reach and send a quick message when I feel tired, or set a short alarm to remind me to check in. If I'm too tired to text, I'll say so before I lie down. I want you to feel seen and respected, not like an afterthought. If you'd like, I'd love to make it up to you—whether that's taking some time tonight to really talk, planning a cozy night in, or whatever would help you feel better. I want to hear how this made you feel and what would help rebuild your trust. I'm here and ready to listen whenever you are; I want to do better for you.
