So basically what I want to accomplish is to get the girls to still be interested or engage basically.

I am not from the United States nor Europe, (I am from Costa Rica. so I don’t know if it is a cultural thing or an age thing I am 20 and girls I talk to are 18 to 21 generally, I actually kind of suck at texting so I get bored really quick, since I think that all the talking should be made in person, but generally if I just stop texting a girl, I feel they think I am not interest or something like that. Any help or advice with that?
