It sounds awkward, but if you think about it, it is more exact than "like". What does "like" mean, afterall? What you think it means and what someone else thinks it means might be different. Saying she has "positive feelings" is actually a bit better because there's not as much wiggle room (one can't say, she just "likes" me, implying that it is a smaller, inferior situation to love or another emotion) and you know it is multiple, feelings. Like isn't really a feeling, just a vague mishmash of positive regard?
