Dude I say this lovingly, but I'm feeling smothered just talking to you about this girl. You've posted about this same situation for the last 5 days, what else are you looking to hear from people?

A week charged with that good New Relationship Energy = future discussed, cuddling, making out, and feeling fucking awesome. But it's just an energy spike! It's not indicative of long term power levels. She sounds burnt out with no libido, sounds like the more nightmarish time to start a new relationship, let alone with someone who comes off as emotionally needy as you do (and I say this in solidarity as fellow anxious and emotionally needy person lol I know I have scared off potential bfs with this behavior).

If you think you have the ability to be casual about it like "hey I'm really enjoying spending time with you and I care about you, I'd like us to be exclusive" I think that's how you could bring it up. But if you're gonna bring heavy shit about long term future commitments that you want her to make right now, then just walk away for both your sakes. If you really feel like you're just a second choice to her, don't put yourself on the back burner! Walk away, save yourself the head/heart ache and focus on meeting new people!
