Im going to be alone forever.?

and this is not a whiny post, i will, i know i will, and i accept it. but sometimes it gets to me. The dreams i have do not include the typical lifestyle of someone who has a wife and kids. Not that i dont want one, i do one day, but i don't think there will be rooms for it in my life, and it saddens me. Im in the army now and will probably be for another 6 years or maybe more, then i plan to travel as much as possible, and i will live on a sail boat for while doing so. I don't think ill be be stable enough at any time in my life for someone to stick around. how should i convince myself this is okay?
