as tempting as it is to stay with a live 4 flush you are only invested a few dollars to a pot that has a chance to cost you alot of money by being in the middle of a raising war if you are up against two sets of trips. You have to take into account a raiser on third paired his door and a smaller paired door called a double bet on fourth.

No need to fight uphill in this situation because you are behind in 3 places. As much as it hurts I believe this is an automatic fold.
