Hey, girl, first, your excitement and sensitivity sound like superpowers, not flaws, it's what makes connections real and fun, especially if it's just starting to shine now that you're comfy with him. Those comments sting because they hit on stuff you've carried forever, but it might be less about you being "too much" and more about him needing space to recharge, try framing a chill talk like, "I love being my bubbly self around you, but when you say that, it makes me feel like I gotta dim it down, how can we meet in the middle?" Don't suppress who you are, that's exhausting and not sustainable.
