I missed my chance to date someone I deeply care for - now I'm struggling to live.

Hello!

Not long ago I asked out girl that I really like. She replied she is already dating someone and so it seems that I have missed my chance.

It all began in the end of December 2016, we chatted on Facebook until on January 5th I was back to the city she lives (and I study) and throughout January we met some 4 times. We spent such a lovely time on random trips to random places (mostly we met for 4+ h), however, without understanding what is a date and why should anyone ask out someone theyve just met, it did not occur to me that I should ask her out (all previous relationships I had, started just by meeting frequently with those girls without stating meetings as dates).

She went abroad for some 20 days, she was sick for some while, so I was able to meet her only briefly on February 28 for 2-3 hours, still it did not come up in my mind to ask her somewhere. She once again went abroad and I was able to talk with her on some March 20. On March 25, I asked her out. Then the bad things started. We talked over my struggles, and as she said she liked me for a while but those feelings somewhat diminished over time because I did not ask her out or in any way advance these things, so at the end of January started to date someone.

It has been two weeks now and I think that she was my One – I think I could marry her someday in the future but I messed it up. I cant eat, have some weak sleep in night and spend most of my time thinking about her.

What should I do – wait for her and hope that her 2-month dating partner changes his mind or whether I let her go, despite I have strong feelings for her?

PS. I'm nearly 22 now.
