Another way might be to tell her that you have feelings for her, and it is exactly for that reason why you'd readily respect her and patiently wait for her to be ready. That way, you're expressing interest without pressuring her to start a relationship with you. This advice is based on what you said that she currently likes you, if that is the case then she won't be scared if you tell her how you feel, and since she does not feel rushed by you, i believe she'll give you a good chance. This situation requires patience from you, but it is important to let her know she means something to you
