Is it normal to want to have an romantically lover and a mother figure

I always want to have an older woman to be my mother figure. And i am currently having a crush on a woman that are 35 years older than me. She is 63 and i am 28. And i sometime want her to be my mother figure yet sometime i want her to be my romantic lover. I know the age gap between us is huge, but i don't care about it. After all, age is nothing but a number right? She is my facebook friend and sometime we talked. She lives in the other side of the globe. She is cool with me being in love with her and she is concerned about my mental health. :( Sometime i think of her as my mother figure, yet sometime i am curious about kissing her and how does it feel to be with her romantically. I feel so confused inside.
