Saturday I went out with a girl for the second time in which the first time we went out was about a month prior and since then she didn't contact me to schedule another date-- at the end of both dates, she said she enjoyed herself, thanks for inviting her, etc in which I didn't close the date good in my opinion; I said something in which she interpreted wrong and I also didn't mention for us to meet-up again (I don't know why I didn't)

On the date, I noticed IOIs such as her conversing when I wasn't, her mannerisms, her wanting to know what I have been up-to, etc.

After I dropped her off, I went to stop by my cousin (who is her best-friend) since I was in the area, and she hinted towards us being "perfect together" as I don't share my business/whereabouts whereas the the girl is nosey

Apart of me tells me that if she was interested, she would've reached out to me since the first time we met in which she didn't, displaying her low interest level-- am I right on my assessment on this despite both dates going relatively well and her seemingly happy/interested in our interactions? Where should I go from here other than working on abundance (mentality and with girls)?
