In a scenario, if you met someone a few days ago for the very first time and then you met again today and after spending time together, you feel lucky to know him/her because you think you will get on well with him/her in the future and help each other. How would you tell him/her it today. Note that, it is not important to meet at a specific time. This sentence could be said in tenth meeting or even one year later after the first met.
I am/feel so lucky to have met you.
I am/feel so luck to met you.
I am feel so lucky to meet you.
