A general rule is when a girl (who you haven't fucked yet) gives an objection for a specific day, just pick another day. When you try and convince them to hang out on a day they've said no to, it comes off as desperate and the chick feels unheard. Also, always important to have shit going on when a girl asks what you're up to on a day, even if you're free for a date, "I'm working out, then cooking. I'm free after 7 though..." for example
I agree I was feeling needy after I sent it and it definitely wasn’t the best choice, I appreciate the advice, anymore advice on how I should advance from that last message I sent?
I would actually try to walk it back honestly "haha, i meant 'on a day that you're off'". If it's been a long time since you texted your last message it might be too obvious though.
