Text messaging is often a way to communicate with someone while avoiding making a commitment to really get to know him or her. The person maybe curious or may have a liking to you, but that interest is on the low calorie end or possibly still developing. I believe people who are shy or nervous talking to you will go with the text option first instead of calling. But, if we are adults, and matures ones at that, we would go about matters via verbal communication.
I think some people avoid talking on the phone because they may end up really "liking you"
It’s hard to get to know someone via text because you can’t hear the tone of their voice, the choice and depth of their words or the emotions that go into them. Text messaging is an easy way to hide who you are but it’s also an easy way to leave room for misinterpretation. How many arguments or relationships have ended due to text messaging? Having arguments through text messaging or emails is juvenile. You’re sitting on one end of the phone sweating with an angry face cursing the person out in your mind while typing that angry text message or email.
I bet they are many people who have exchanged numbers with someone out of interest, but can count the times you actually talked to that person on the phone. If you’re not interested, say so via text since that’s the way you been communicating with that person anyway.
Yes, there is a possibility that the person has a lot going in their personal lives. If that’s the case, give them space. If that person is interested in you, they will pick up the phone to talk—even if it’s for 30 quality minutes.
