Am I Still young ?

I am 22 years old, I have got ASD and I am just wondering that am I still considered young. 

Basically, I met this guy through one of my closet male friends(he was 18) when I was 17 and he was 19, we had small talks, a year later until when I was 19 or 20 when I and my closet male friend always go into the supermarket (Sainsbury's) just to get snacks and stuff before having our lunch and him and his mate talk when he was in the shopfloor and whenever my mate goes into Sainsbury's. I have seen this guy around in Sainsbury's before he left last year ago. 

Years later before Christmas and after my 22nd birthday, he added me on Facebook then a couple of weeks later I suddenly recognize him from my male mate and communicating more. He said he really likes me and wants to have a date with me after we get to know each other and I feel happy emotion.

I wish I should exchange this number at the time when I was 17-20 years old. I was with my ex from when I was 20- 21 (last year he dumped me) how I met my ex was through social media which I kept the secret part from my family and I met him with my other male mate and he knows my ex btw I was 19 and he was 25 when we first met. 

I did a big massive mistake, I feel like everything is too late for me and I feel like I am not young. If we ever get together I feel like we are not a young couple. I hate delaying myself.

Am I Still Young.
