How can I be more romantic and cute with my beloved girlfriend?

at first me and my girlfriend were just friends, her being taken by one of my friends, but she broke up wiht him for me, he still doesnt know why they broke up, other than hes an asshole to a lot of people.. any way, we are together now, 6 months yesterday, and we got sorta physical with each other, and she seemed like she liked it.. i called her the night before and she told me she wanted me to do it, so i did. but later last night, she was upset, and i think she isnt ready to be physical yet. she said that i was too touchy.. she compaired us and her sister and her bf, and her dad and his gf.. and they dont really touch each other... so she thinks that its wrong to touch and be touchy with her.. so i was wondering is it me? is it her and is she not ready even after she thought she was? did i make her uncomfortable enough for her to not be ready? I love her turely and i want to show her it. we said together that if i did do stuff to her, it was showing how much i really cared about her and that i truely loved her and her letting me showed she loved me the same back... but now that she doesnt want to.. does that show me that she doesnt care anymore, and that we should only be friends, or is she just not ready and still cares? ughhh i dont know what to do, and i cant break up with her.... anyway, how can i be romantic to her, what are little things that shed love? by the way, i dont have like any money, so.. it kinda has to be cheap to free.. and i mean i know some things.. i made her family cup cakes the last time i was there and we had fun, and she had fun wiht me accidentally pushing her into the snow yesterday and she dragged me into it too, but what else can i do to make her happy? how can i show i still care about her so much, that im in love her with my whole heart, but not get physical with her, and not offend her because i dont have any money? i know that she likes when i play guitar for her sometimes, but i need to know some good songs that arent too hard, but are romantic to play for her on an acoustic guitar... if you know any, thanks so much, or if anyone knows any guitar chord progressions for a song that i could write about her and some help with lyrics and i cant sing.. so help on those would be greatly appreciated haha, thank you so much thank you thank you!!! and thank you for any one who provides any useful information to my delema... i need to get out of this rough patch going on between us because its making us both really sad.. and i need to cheer her up a lot.. so thank you and i love you to anyone who helps me out in this situation.. thanks!!!!!!!!!How can I be more romantic and cute with my beloved girlfriend?
