This girl and I talk on the phone every night for like three hours and hang out at least three times a week and I was just wondering if that is a good enough hint for you to go ahead and ask her out?

Answer 1

yes but do it quick before u enter the friend zone with her =]

Answer 2

It sounds like you both have a strong connection through frequent communication and spending time together. Asking her out could be a natural next step to explore the potential for a romantic relationship. Pay attention to her reactions during your conversations and hangouts to gauge her interest before making your move.
