Brief: Was planning last minute trip to the tropics this weekend, jokingly asked a girl I dated a few times to go. She said she'll try and is trying to get an extra day off. Later she texted me that she may need to stay separately. WTF!

Background, we went out on 3 dates approx 1 1/2 months ago. I may have been over the top on 2nd date and it soured things. Made out the remainder of evening anyway but she brought it up on our 3rd date. At the end of the 3rd date she gave me a little gift from an inside joke we had when we first met and I didn't remember it and she hamstered hard and I was able to hold her calm her escalate to make out. I was just getting back into the game back then I didn't close her yet. Since then we've only been texting. I've dated over 20 or more girls since then and try to practice abundance.

Tonight I asked her to go on tropical vacation with me tomorrow, told her I'd pay for our room (I'm paying anyway so). She's currently looking into getting the time off to go.

All was moving insanely well until 3 hours later of working on logistics she said Her: "I may need to stay separately from you". I think, WTF! Me: "We'll stay together. You know we'll have a good time." Her: "I'm not sure I'm ready for that yet. You are?" I realize this is LMR and I need to build her comfort level up and give her the opportunity to "let this happen". Me: "I'm attracted to you and like spending time with you. Let's see were the weekend takes us." Was worried about beta tone but, felt comfort was the priority here. 40 mins later Her: "I'm not easy to stay with. I've been told" "I'm on a different schedule.""How early are you flying out" Still LMR, or is she down now, I need to build more comfort or WTF!

Additional note, she had mentioned twice that she was still trying to work out the extra off and if I just wanted to book my flight. She also generally seems spontaneous and recently did "girl weekend" in Vegas so there's that.

Questions: How do I overcome her LMR? Am I on the right track? Should I abort and just do my own thing? I need to be booking this tomorrow and leave tomorrow night or Sat morning.

Edit: update and format

Update: She said "looks like I'm calling out sick Monday". So for now looks like we're a go.
