Cos there's a definite chance she's simping for someone else in the meantime and you're just a backup for her so she gives you fodder for a few minutes in a day so you don't leave.... A woman who really likes you would stay awake late in night, push her limits, try to wake up early so she could just have a few more minutes with you. Trust me. If it's not a FUCK YES, then take it as a know and keep this in mind, FUCK YES isn't just words. You need to look at her behaviour. If her behaviour doesn't give you that FUCK YES vibes, don't go ahead with it.
