What do I do if I don't only want to text I want to have a phone conversation?
That's understandable. Whats your reasoning for not wanting to text?
Something about texting only seems like I'm avoiding the issue of calling.
It makes sense if you would prefer to call over text. If calling is something that you feel you are avoiding to do, then completing the phone call will without a doubt make you feel better. This is a great reason for you to opt for a phone call over a text.
But there is a problem, I really cannot afford long talks so I cannot talk for a long time when I call.
Since you can't afford long calls you should opt for texting until you save some money. However, just remember it's okay to prefer phone calls over text.
