UPDATE!!!!
Just had a wonderful chat with Marc. Now taking a break to have dinner, might go on talking later, else some other day.
I was not really planning on it, but the topic of meeting up naturally surged after a while and I asked him. He seems to be okay with it. Seems we're halfway there
here's what we said (we first talked about how expensive everything is in Switzerland, even travelling and such. Then I asked if he drove a lot outside of Zürich, where he lives, to which he said no. Then we went on like this) :
(Me):
To Vorarlberg you drive about two hours, from Zürich. At least that's what I heard
(Him): In car?
No, in train
Would be okay
With car a bit faster
If it's okay, you could come here some day 
You'd be welcome
Thanks
But if, I'd probably come with my flatmate who has a car. Would that be ok too?
Sure
Depends also on how long you want to stay
Only for coffee or some beer?
Or longer?
Ufff, no idea
Otherwise I could also get you a room for a day or two and you could explore the area in peace
I mean, that way it'd at least be worth the travel
I'd say we plan that when it's time. But will be difficult for me in the next weeks
Doesn't have to be right now. Just an offer.
You did say you wanted to escape some day
Yeah, generally a good idea
but in the moment I don't know how I should manage with the time
ok no problem
well, maybe someday around Christmas
for example
yeah, I'd have semester break then
we'll see
would be nice if it worked out
we'll have to see
but basically it's a great idea
then maybe we also get to know each other personally. Would be nice
only if you want to, of course
yeah, now that we've already written so much, it's about getting time 
and they were intimate talks too
yeah we've talked a lot
I hope that'll also work IRL
are you preoccupied about that?
maybe a bit
I met my best male friend on the internet and we got to know each other about a year later
and we've been best friends for 13 years now
So, seems good... or do you think I was too forward? Anyway, thanks for the help. New advice always welcome!
