do not go out with any of them. Go out as a group, with friends, so you have an opportunity to interact with each girl and find out who is a better match. Do not invite all three girls as this would be funny but NOT NICE. Ask each girl to go with a group of kids to an activity where you have time to talk and enjoy each other's company. The fact that you "want" to date all three means that you are not ready for dating. They point of dating is to find a potential life partner. Some people see dating as a game or date to see what they can get out of it. This is not what a "nice" person does. A nice person is in a relationship for the benefit of BOTh parties. Until you are ready to find a life partner you should not be "dating". You should enjoy time with friends socially in a group setting. I know that not everyone will agree with my advice, so no need to explain why I am wrong. I am old enough to know better.
