Is it normal he wants to stay in touch

Back when, I wouldn't have had any problem investing the time and effort in getting to know a girl who lived some distance away, if I thought it might lead to sex down the road. And it's so much easier today, with the internet and texting!
Of course, with so many who haven't a clue as to their sexuality and preferences, who knows what this guy's motivation actually is.

He wants to be sexting buddies ;)

BE CAREFUL!

If you are both attracted to each other then you've probably already discussed the possibility of it turning into something more?
Is that something you feel strongly about one way or the other?

Males & females can be just friends but it's rare in my opinion. Normally at least one persons feelings are beyond friendly.

& similarly guys do contact women online just for friendly chat but it's also rare.
I'd say the fact he is still speaking to you so often after 6 months then he is at least somewhat romantically interested in you.
Hell, anything over a month of daily chat shows a high level of interest or intrigue.

Personally I think if you're enjoying the conversation & the friendship then don't stress too much about his intentions until he makes them clear or you want to share your thoughts with him.

This is so common. Either he wants sexting or just a friend to pass the time but not sharing his life with you is dodgy. You're probably having feelings for this guy and I think you should drop talking to him soon or you're just gonna get disappointed. Long-distance doesn't work if no ones prepared to sacrifice it.

Y'know, there's always this possibility that some people just want to be friends. Not everyone in the world has the motive to fuck you.

Also, keeping contact for a long period of time isn't enough to know if they want a relationship with you or not.
