Well I met a different kind of girl. She is really beautiful. Never been with someone that beautiful. We went for a date and couple days later we chatted in a bar for long time. She was always kinda neutral towards me. She didnt give any clear IOI. She did seem to wanna hang out and chat with me. So we set up third date and it was yesterday. Again in that date I tried to get close to her but again she was very neutral. Later that night we went for a swim. Water was pretty cold and she reattly took her time. I tried to hold her hand but she didnt take it (was afraid that i was gonna pull her in the water). I tried to put my hand in her hip but she said my hand was too cold.... Damn. So she didnt give any clear IOIs. She didnt respond to my touching at all. She didnt maintain eye contact. She didnt ask many questions about me. and so on. It was weird...
Why I still thought that she was into me was because she did go to swim even tho it was actually big deal for her (she actually celebrated it) And before swimming we went to this ski jumping tower wich was actually kinda hard to get. That girl also had fear of high places. And before I had told her that I like adventures and brave girls. Also she did kinda talk nervously. Tho every time I was trying to talk about something "deeper" she just changed subject.
Well after swimming I thought that Im just gonna go through with this and see what happens. I asked her to my place for a drink.She agreed. I was suprised she agreed. We had a drink and talked for awhile. Finally she was able to talk about something deeper about herself. Then I decided go for a kiss. I said to her to come sit next to me. Then I told her to look into my eyes (which for some reason whole day had been hard for her) She asked me why and I told her because Im gonna kiss you. Then we kissed.
After the kissed we talked and kissed again and again. Aaaaand we had sex. And when we had sex she finally showed some excitement

She was really into it.
But what was weird and got me thinking was that she didnt really give any signs that she was into me. Normally I would have just ended the date but I really wanted to go all the way. If I wouldnt have asked her to my place nothing would have happened.
Also what is weird is that she was really beautiful and probably has many mens on the line for her. For that reason expected different behavior.
What do you guys think? Has this happened to you?
