Am i setting myself up for heartache?

i met this guy two years ago on an app on my phone.we would txt and talk on the phone before but i never really got too involved since i mean he lives in florida and i live in texas i guess i just talked to him whenever i didnt have anyone else to talk to or something.we traded pics etc through emails and eventually lost contact. recently idk how we ended up being friends on facebook and ever since i sent him an IM we exchanged numbers again and we havent stopped talking.this has been goin on now for like three months on a daily where we talk and txt through out the day.he currently has a gf but he says he likes me and is trying to come out here and visit.he hasnt been able to visit me for reasons him and i know and i totally understand him. if hes ever actually able to come and visit i kno we would hit it off but overall i dnt kno if this is right since i have my life in texas and he has his life and a gf in florida...any advice???i find myself thinking of him a lot and i become impatient when i dnt hear from him :/ perhaps im involving my feelings too much.no one seems to understand my situation :(
