Hi Carena, I hope you don't mind me replying, I was going to stay out of this subject and leave it alone to the woman. But if I may... I would like to think that there are still some nice guy's out there and I am sure there is.
I know of, is don't try to hard. Apart from that, us guy's are fairly easy going. We always think it is the woman that are difficult to workout.
I can't help you on the "opening up for hurt" part. It is something you just have to do. If it doesn't work, DON'T TAKE IT PERSONALY! is the most important lesson you can take from it. You just have to move on. And, don't be afraid to be honest with your feelings and intentions, as long as you don't come on all thick and heavey.
HAVE FUN! is the important rule
. A guy wants a girl that is just plain fun.
As for the dating thing again, I feel for ya, I would hate to go through all that again. But I don't think anything has changed. You just need to find a guy that is like minded.
Don't get forced into any situation you don't want to.
