Ok so im reading the book The art of Seduction from Robert Greene and i know its important to start slow and take the time and approach indirectly. But here is the situation. There is a girl that took my breath away from the first moment i saw her (on the buss i think or somewhere) it really was the most beautiful women i have ever seen but thats beyond the point. Well for some lucky coincidence i got a job were she was working. But because i was afraid of fucking it up i didn't make any progress. Unfortunately i wanted to find something more meaningful to do so i left the job. I was sad because that meant i had to leave her (not that i made any progress anyways). But then after like 2 years we met again in a party talked just a bit and that was all. Now its been like 2 more years and i still can't get her out of my head. I know its needy and stupid but i just can't. Now we live in different cities and i got this dream about her and woke up and realized that i need to have this girl. I know it will happen eventually because i know but i just realised that its her birthday and im wondering if its a good idea just to tell her congratulations with a smiley. Just that, i know its important to be indirect and do it safer but cant this be like something that can help me in the future? Casanova and don juan used this after they saw girls again after some time (i know they had story with them before so its different) so im wondering what is the right approach?

Right now im not in my prime and need to get in shape and get my confidence back up and im working on it. So i don't feel confident enought to take it beyond a "congratulations". Its the most indirect approach i can think of. I don't even know if she has a bf but it don't really matter. I will continue my life improving myself and i know we might meet again later on and ill get a chance but should i pass this one? Even tho i don't plan in taking it further, than that because honestly i have no confidence right now and we dont even live close to each other.
