Can i travel to U.S for 85 days then go back home (U.K) then after 2-5 days go back?

[kingleon312]

Entered the U.S on a ESTA. I am scheduled to leave around the 90 day mark, (about 80ish days out of the 90). I plan to travel back to London for easter, (so i will be in U.K for around 2-5 days depending on flight prices) and then travel back to the U.S for another 85-90 days on the ESTA still. Will i have any problems at immigration at the airport? i called the embassy and they told me they MIGHT ask you why your going back so soon and to take any evidence with me supporting the fact that i will not overstay and will go back once my second 90 days is over. The evidence i have for this is my **already confirmed** university place starting september 2015 in London.

Will i have any problems? am i just overthinking?

thanks
