Welcome to the forum 
I am sure your intentions are well meaning and a lot of guys will do exactly what you just wrote. We like the girl, not only is she adorable in our book, but she’s smart and guess what? We want to have funky-monkey sex with her and its OK to feel that. In reality its healthy and good to feel that initial infatuation towards something we haven’t yet touched.
So if you’re anything like the rest of the world you totally want to buy her things to show her you care, do nice things to show her you care, be the guy she can rely on to show her you care. It’s all with a pure love-stricken heart that most guys do this.
One of the most valuable lessons I ever learned about woman, from get this: a woman. Yep believe it or not a woman! This girl I absolutely loved and really wanted I did everything I could to show her I cared. One day I got up the balls to ask her why she just wanted to be friends. She told me I don’t ever really do anything nice for her! WTF!
I was mad and told her I did everything nice for her to show her I cared. With her big brown eyes and that smile that touched my very soul she said you do things to show me you care, but you don’t do things because you do care. She was right, 100%.
My actions were being taken as manipulative acts of a desperate man looking to find love from the one girl he thought was an angel. I don’t think they started that way, I think I had the best desire to really be a cool guy for her. But it was all done with an outcome that was predetermined by me. I was doing these nice things for myself rather than completely giving of myself freely.
I tell you this because she wants a man who while is sweet and gentle, also has boundaries and limitations. Will hold the door and her chair, but is going to tell her no when need be. Be THAT guy, the guy that she is going to feel safe and comfortable around. Unpredictable, keeping her guessing, but alluring and fun.
Gently grab hold of her hand and pull her towards you. For an awkward second look deep into her eyes and then push her away and with a sly smirk call her bad. There are lots of things you can do to “show her” you care and none of it costs money (and I don’t know that you are or not but this is a generalization that might help others too). Pull her in, push her out, build attraction through your actions
. It’s a valuable lesson I learned and it has dramatically changed my life.
You really haven’t told me much about your personality and without knowing something about you its not easy to suggest stuff to you. Ammo is always good, but maybe some A314 might be better. I wanna know about you and how you are. What’s your race, are you shy, talkative, friendly, the serious one, jokester, who are you? What is your physique like? Help me and I will help you?
