Advice from Capricorn women please!

Hi, pisces male here who has met a cap. woman online about a month ago. Some additional background: we are both single parents as well. I had never been into astrology much before but in the last year have found there is some truth to the personalities of each sign. She seems true to what I have read about cap. women: ambitious, has her priorities in order, works hard, does not share feelings much, etc. We have communicated pretty much everyday usually by text. She is not one for a lot of texting which seems to be another trait of caps. We have spoke on the phone a few times. We met the first time for coffee and 3 hours went by like it was 5 minutes. When we left I told her I definitely wanted to see her again and she did too and we hugged. The second date was supper at a nice restaurant and the night ended with a kiss and us holding each others hands and looking at each other. I know she is interested. Today I left a note in her mailbox telling her what I admired about her...nothing too romantic, just wanted to let her know I was definitely interested in her. She texted "she came home to a sweet letter in her mailbox".
I have read that cap. women will take a while to warm up to a man and to be patient and that they also may like their alone time. That is fine but what I am concerned with is that from time to time I see that she has been on the dating website. I wonder if she is still deciding on me, or if she is checking if I am online? I have read that caps can be insecure and not looking for a "player" so maybe she wants to make sure that I am not dating 20 women at once. I'm not, I only want to date her!
My thinking is if she was not interested I would have stopped hearing from her and the note I left today would have been a turn off. Am I on the right track? She is so awesome!

You should put this on the Cap board. You'll get more responses. 🙂
