As written in the title, I'm frustrated right now.

So I met this girl 4 years ago and we recently began to see each other again. Long story short, I saw her last weekend twice and things were pretty hot, we didn't have sex but she would always say things like : "I want it in my mouth" and that kind of stuff.

Tonight we had dinner together and proceeded with a movie at the theatre. The things is, during all evening, she kept responding negatively to my approaches, the "feeling" that we had between us this weekend was gone. So right now I'm like : "wtf ?"

I accompanied her back to the train station and even if there was 6 minutes before the train left, she had already stepped in the train. So I asked : " okay, there's 2 solutions, either you are very tired and want to sit down, or you want to leave quickly". She jokingly said : " a little bit of both". So I said :"okay, have a good night, see you" and walked away, trying to play it cool.

But right now, come on, wtf man ?

I won't text her in the next few days, if never, I have other business to care of, but Jesus, can anyone tell me what is going on in her head ?
