We met online and have had lovely conversations and have talked about meeting soon. He has one month left before he will be leaving to travel a bunch, and he will be gone until January. Is it stupid to meet him and possibly start something? What if we don't meet until 2 weeks from now even? Will it be silly?
Risk it for the biscuit? There are a lot of pros and cons. He may not be loyal while traveling, if you have a lot of doubts about him or this decision then you need to go in without them. Remove them from mind. If you think you won't be able to do that it's not worth, relationship needs trust and communication. He may also be completely different in person than you expect him to be since people can be more comfortable online or be very two-faced, creating another personality entirely. Your choice, I'd say go and find out what he's like and decide from there. Risk it baby!
It doesn't hurt to meet him. Don't get real heavy into anything till he comes back though. He might change after getting out in the world. He might want to move somewhere he's been and you don't want to go there.
