You can always put what I call "feelers" out there and watch for her response. Place your hand / arm on her shoulders, hold her hand, give her a quick hug, a kiss on the forehead, etc ... She may not directly acknowledge the act, but watch to see if she was comfortable with it or not. So long as she doesn't pull away or cringe, then continue touching working towards acceptance. You'll know she's accepted it if she starts initiating contact too.
I would stay away from ILY's until you hear it from her first, but that doesn't mean you can tell her you missed being around her today or that you've been thinking about her.
