My best guy friend moved away

So my best guy friend moved away and I don’t know how to cope.

Let’s get a few things clear first:

- He’s 21, I’m almost 19

- We are both in long term, long distance relationships

- We both left our home countries to work in France (how we met)

- We’ve never ever had feelings for each other, admitted there’s an instant connection but nothing more than loving as a friend

- I knew from the moment I meant him that his contract was ending in March

- We’ve seen each other everyday for the last month

- We are completely clear about how we feel about each other, there’s no secrets, we’re simply the best of friends who love each other dearly

So we met because of work and we have a few things in common, from the start, we clicked and just had an instant friendship so we starting hanging out. A coffee turned into a movie, a movie turned into 3, that turned into a drink, a drink turned into a night out ect. And we are now the best of friends.

I am a very insecure person and he made me (with lots of persuasion) come out of my shell, feel (a little) more confident and overall enjoy life away from home more.

He was the only person here that I considered a “best friend”. Everyday after work I looked forward to hanging out with him and we had an extremely special friendship.

Last night I saw him for the last time, his contract has ended and he left for his home country this morning.

Honestly? I’m heartbroken, I don’t know what to do with myself. I miss him so much already and it hasn’t even been 24 hours since I last saw him. I’ve been looking at videos and photos of us since he left and I’m so upset every-time I think about how beautiful the time spent with him was but how hard it was to say goodbye.

I know he’s happier back at home with his family, friends and girlfriend. It’s what he wanted but I can’t help feelings so lost and worried that we won’t stay as close. I don’t know when I’ll next see him again.

Any advice?
