Dating

Am I overreacting or is she pulling away? I feel like she's sending me mixed signals?

Dating a girl for a month. Had 5 good dates. First 2 she was chatty. We were flirty on text. She sent me Snapchat of herself, "I would do. I hope you have a great night!" I replied with a pickup line and also said I would do, too. She was different on the 3rd date. She was shy, nervous and dressed down. She was a little hung over from the night before. We hung for 5 hours. She opened up about her family and herself. We had our arms around each other towards the end of the date. I dropped her off at her car and kissed her passionately. She said text her later that night. We text all week after and even sent me a flirty text, "I could get you to watch a Hallmark movie with me." 4th they sat us down at a high top next to each. She moved across from me. She was nervous. We left, and I put my arm around her and vice versa. We sat on a bench with ice cream. She relaxed and laughed at my jokes. We kissed passionately and she was smiling. I had a text from her when I got home. We went out for 5th last Mon. I gave a hug and kiss meeting. I drove downtown to a rec hall. We sat at a bar and she was quiet. The bartender asked if we signed up for VR. She said, "NO.. we're not ready for that." I thought that was weird. If you're not ready to play a video game with me, then why the flirty text's? He said, "How many dates is this? "Um..4? Maybe 5?" I said," It's 5. I'm glad someone is keeping track, haha." We had a great time playing mini golf. I flirted with her and would poke her in the butt with my putter when she tried to put her ball. She would laugh and blush. I reached for her hand and she reached for mine. I kissed her passionately at her car and tried to escalating. She was hesitant. She text and asked if I made it home. She told me she had fun. Asked her out last Mon for last Thurs. She was traveling on Thurs. She had plans in the air this week and offered to go on a hike me this Sunday. I accepted. The ball is in her court to tell me when she's free during the week.

Continued-She has been a little more distant and less flirty on text. I thought it was weird that she asked for a date a week and a half out after 5 dates? I feel like I need to back off. Is she pulling away to ensure I keep my composure, nervous from past experiences, or is trying to determine how she feels? She hasn't told me what her schedule was for this week and don't plan on asking. I feel like she needs to tell me what her schedule is this week if she wants to see me.
