Dude,
5 years ago i used to hang out with this girl all the time. She liked me and i liked her but it was never the right time because we were with other people. Then she went away to school and Buh Bye....
Now 5 years later, she apeared out of no where, and the hardest problem I have is deciding if the girl that i have been with for the past 5 years is the right girl (there are other issues there as well) and if i should not pursue the girl I really liked 5 years ago (who I think may be perfection itself).
So what i am trying to say is....
Just do it. Be Honest. Bring up the conversation you had with her from 2 months ago. Ask her if she still feels the same and just tell her how you feel!
Otherwise, you will become a "Should-Head"
(I should have done that or I should have done this) ... Just do it!
Good Luck dude!
