Arrghh what do I do?

[Justfeckoffwiththeovulating]

Serious crush at work.
I'm not attached, neither is he.
Deep down I don't think he's interested. No real signs apart from office chit chat. He is very reserved. Doesn't always reply to my emails.
He is leaving the workplace next week.
Do I do something crazy like write a note and attach it to a mars bar (his vending machine usual)?
I was thinking of saying 'I have never done something like this before but do you want to go for a walk sometime? Here's my number, please don't reply if you're not interested, I would be mortified' but I want to put something in about him not giving me any signs that he is interested incase he goes to his new role thinking he's done something wrong!
Part of me thinks it is super weird and cringey but part of me thinks what do I have to lose?
Honestly this is so embarrassing, feel like 15 year old me trying to decide how to write out my unrequited love's Christmas card to portray the right amount of coolness and desperation.

What did you decide @Justfeckoffwiththeovulating ?

Press ups ?!

Give him a card and a Mars bar but ask him to open it after he leaves. That way you won't have to see his reaction!

Is he on linked in?

Adding someone on linked in on their last day is normal.

Then drop him a message in a few weeks asking how job is going? See how he responds.

Card and mars bar. If you can say to him, if he would like to go out sometime your number is in the card. Then walk away.

If he's as painfully shy as you say, would he be able to pluck up the courage to call you even if hewanted to? Having said that, a shy person doesn't usually drop to the floor doing press ups while waiting for a work meeting to start.

I'd send him a card that is a bit more direct. Something like: Good Luck in your new job. I would never have said anything while we worked together and you have never given me cause to think you feel the same, but I'd really love to go out with you some time if you are free and interested." Then add your number.

I'm still deciding! At the moment I think I'm probably going to be rejected but also there is no time in my life for a relationship. My kids are full on, my job is full on, as is my social life. I couldn't see him on the evenings apart from Saturday or Sunday, so could offer maybe a lunch date every other weekend, who wants that?
