Hi Angie
I am 163cm & 58kg so yes you can kite. 2 secrets to females learning to kiteboard.
1st don't let you boyfriend teach you, they just don't get how girls learn. We don't usually jump in feet first and go hard, we like to gain some confidence step by step. Plus they nearly always forget the basics like safety & let go. So get some professional instruction from an instructor who has references from other female kiters he or she has taught.
2nd is don't go too small too early on the kite or the board. Start off in light wind around 10-12 knots and on a big enough kite that it wont back stall, drop out, fire up and drive you generally crazy. A big kite in light wind is so stable and so easy to learn on. I learnt on a 13mtr Bandit 08 in 12-18 knots. You don't have to work the kite much, you have time to think about the board, the wind, the kite again etc etc. I now ride an 8mtr & 10mtr with a 128 board, but I never would have learnt on either of those.
Feel free to call me or PM me if you have any questions. PS, don't give up it is awesome fun once you get past that first learning phase.
