You didn’t have to upgrade your texting plan.
For some reason, there are men who like to have a "virtual" relationship only, with no intentions of meeting. I don't understand it myself--what's the point, but there it is.
If he can't seem to find time since January to meet you, I think it's safe to say it's not going to happen. It's up to you whether you just ignore him or send an email wishing him a nice life.
