Guitar string always breaking right after restringing it?

It's happened twice already.. I don't know if I'm doin something wrong. I do know nothing is wrong with the guitar, I checked. Maybe its because the string hasn't stretched out yet? If so, how long should I wait before I can play again? Or would I have to keep retuning it back again to standard and not play at all? How long would I have to wait then? Please help me out here haha I'm tired of constantly buying a whole set of strings just to replace 1 broken string.. Oh and the string that's always breaking is the high E. Also what brand should I buy? I play an Acoustic Electric Ibanez AEG10E.
