A month ago I saw a girl I got immediatly attracted to. We talked and everything, got her number, acted c/f, not needy, etc around her, some kino, etc, it went well.
After the first 2 weeks I started to lose the interest I had and she noticed, so after that she started to have the initiative of talking to me.
I must say I acted kinda AFC (just a little) and said to her about 2/3 times indirectly that I was attracted to her, but there were some things about her I didn't like. She acted self-concious, but everything went well.
However, at the last 2 weeks I don't really know why, but I got the feeling she was trying to manipulate me.
She sent me sms like 2 days apart for no apparent reason. The sms were like "hello, how are you?

", "I liked to invite you to lunch with me, but you always have a lot of things planned, so I lunched with some colleagues. I can't give you so much trust ;D" or "hey, what are you doing tonight? Are you going to hang around ou will you be at home?".
Everytime I answered she did NOT answered back, which I thought was weird, but I've never asked her why.
I always answered her like 1/2 hours after she sent the sms.
The answers were funny, such as "hey, tonight instead of hanging around with my friends I'm doing yoga...".
From my initiative I invited her to 1 lunch with common friends (because she flakes when I invite her to be alone with me) and she said "oh, thanks, I accept, but I'll go with a group of colleagues. If you wanna come with us you're welcome!", which I replied "thanks, but I'd rather lunch with my friends

".
Last sunday we had a conversation in which I told her half serious, half kidding that if she wants to invite me to something then just stand up and do it, but she took it serious, so I replied saying something like "didn't you notice I was mocking you? you're really a lifeless girl!

", then she answered very well and everything went good, including me playing some c/f like "oh god, don't you see it doesn't matter how hard you try? Do you like to be dumped by me?

". She engaged it well.
Anyway, do you guys think she's manipulating me? I'm like no more interested in her, just a little bit. And I think I'm keeping her to her toes.
Also, when she sent the sms ""I liked to invite you to lunch with me, but you always have a lot of things planned, so I lunched with some colleagues. I can't give you so much trust ;D", the conversation was:
Me: "oh, what number am I thinking? Just to see if you are right again."
Her: "I say one number and you tell me I'm right and how fantastic I am for guessing right everything about you, yeah, I already know that game kiddo

".
Me: "well, it seems you've already figured everything out, you just forgot to answer the question

".
Her: "number x"
Me: "you're wrong. try again looser."
Her: "you think I'm here playing lottery

"
Me: "well, I was trying to find somebody to play lottery with me, but it seems like you just don't fit

"
She didn't answer...
