how do i show the other side of me

I have the same problem. It depends what you mean by girly and romantic. For me, I generally tend to be a pretty apathetic person but when I do want to be romantic I will just cuddle with her. I would wrap my arms around her waist and lay my head on her shoulder and just tell her how much I love her and I would kiss her and just make her feel loved. I hope this helps.

Dont worry about showing HER that side yet try to show yourself that side first and when you;re ready then show her.
