Quick question: how do you know it’s love?

Monica • A virgin 20 year old Muslim, not that shocking😂

So I met this guy online about a month ago. We’re on different timezones and have 12 hour difference. But somehow we managed to talk all day and night despite that difference. Whenever we decided to talk on the phone or video call my heart literally pounds and I’m all giddy and excited and blushy when I talk to him. I don’t know how do you define love, and not too sure of what to call my feeling is. I just tell him I care about him so much. I’ve never had any boyfriend before, so this is new to me.
