Whats in guys mind really

Guys im raising my white flag needing advice.

Im a 22F and have a crush on someone at work
(21M) for over half a year now.

We were never close throughout and rarely sit together, i was also away for 4 months so there was 0 contact between us, i almost thought ive got over him until one day he came into my dream and we were dating 🥺💗 when i woke up i go 'urgh looks like im love again.'

I will be away again for another 2 months so yesterday i finally got the guts to text and ask him to grab lunch tgt before work, but he said he got a busy morning: (i offered to grab ☕️ tgt sometime but he didnt even put me on read my text (cryTwT) ive never initiated before because i was taught since little to not do that as a girl, but yea at this point i reckon i need a breather here to take in all this..

Idk how to face him rn at work phewww. Luckily i was prepared and only ask him out when im almost leaving (will return in 2 months so i guess its also good for me to heal myself with time ;-;

I guess he's just not The One if he don't reciprocate my energy. But i would like to know still do i have zero chance based on everything happening here?

Fyi i came out from my past relationship a year ago and i sometimes tell my coworkers sitting around me. I couldnt remember if ive told him about my ex (bf that that time) or if hes aware
