What would you do?

I have been talking to this man for 3 weeks that I meet on a reputable dating app. He's 31 and I am 19 almost 20 he has one kid. Honestly the child and our age difference doesn't bother me. He is also in the Air Force and has been for a while now. I want more from him and want to meet up in person. I told him I'm done being his pen pal and much rather talk in person. He agreed with me but no plans have been set up for us to meet yet. I've been talking to other guys but I still much rather be with him. Should I just forget him and move on?
