Whoa. Visavi, you're very cute!!
I dont think you should go on the date. Especially because you are going off to England and your previous experience wasnt that great. You know, I hear great things about cute Britsh boys
But in all seriousness, I dont think relationships are something to be rushed. Just becuase your friends are dating or married doesnt mean you have to jump on that too. Take your time and enjoy life because you're at an age if you settle down, its probably going to be serious (not to say it shouldn't be). I mean what I'm really trying to say is that you should do what you want, not because you feel pressured by your friends.
Jam it back in, in the dark.
