I have been 'online dating' this guy for months now. I don't know what my next step should be. Advice?

There are a few 'issues' with this relationship. The first and formost is distance, we live in different countries. The second is a substantial age gap, he is more than 10 years younger. Third is I'm a single parent. We have a lot in common, including maturity level and interests. My heart races when he comes online and I experience big lows when I haven't chatted with him in awhile. I sense he is becoming impatient with this arrangement, as am I. We both are eager to be together and have no idea what to do.
