If she lost interest because I didn't make a move should I do this?

I've been seeing a girl for two months and went to her house a couple of times. She would talk about sex a lot and give me signs of interest through body language. The first time i went around she put her legs on mine and i gave her a massage. The second times i went around we cuddled and held hands and got a bit flirty. Third time i went around she obviously wanted sex with me as she wasn't wearing much. I didn't make a move but hugged and kissed her when leaving. I saw her after this and she was being flirty with me again and we held hands.
Last week i went to her and she didn't want any physical contact as i had tried to put my arms around her and she didn't want me to. I still hugged and kissed her when leaving. She has since told me me she's not after anything and is sorry if i got the wrong end of the stick.

I have messaged her again since then asking how she is, but she hasn't replied. Should i try one more time and explain that i do like her and am sorry for not making a move on her sooner as she was clearly interested. And to ask for us to try one more time?
