03'-V6/112k Bad head gasket replacement or not?Coolant in oil,no overheat/leaks

Failed pressure test, oil cap to reservoir was coated in orangish milky substance. Visible coolant level loss and leak spills, thought to be oil but later determined were coolant. What do you think it could be ? I bout 12/2014 used from a dealer as second owner with 104k miles, now 2 yrs later with regular maintenance done and 112 mi. Also, I did have the valve cover gasket and intake valve replaced a year ago, when the car had 106.5k mi.it. With having kept up on regular maintenance & only putting 6k on the car in a yr. with the head gasket in need of being replaced, should I risk getting the work done and keeping the car or sell it now ? Is it possible, that I may be able to affordably keep the vehicle as my sole source of transportation for the next 2 yrs. ? Any readers that have had the similar work up done on their 2003 Saturn Vue 3.0l V6's, please reply with a scenario of your results so I hope I may ease my anxiety level by getting better understanding/knowing more of what I can expect. THANK YOU !
