Girls can you please offer some advice to a guy?

I feel I have have been led on by several girls in the recent past. They seem to have enjoyed spending time with me, one girl even asked me to go snowboarding twice with her after we had been surfing and insisted on paying for everything including meals and drinks and driving (a two and a half hour drive each way). I had paid online for lift tickets each time, but still. I do my best to hide my feelings but when I do show them I am left abandoned. Should I devote my life to my career; is life supposed to suck like this?
