I'm not suggesting that youngsters cannot fall in love.
We have a thread somewhere about just how young some people can be when they fall in love. I think I was nine ~ and I felt that it was real.
My concern, re age, is connected to my concern re the Internet. People ~ paedophiles ~ pretend to be who they aren't, so that they can groom children & teenagers.
No ~ children today are not smarter ~ they are more worldly wise, perhaps ~ but people are people.
But you asked for help and I gave the only response and advice I could.
You have never met these men.
You don't know them, so I cannot see how you could have fallen in love with either of them, never mind both.
I can't see how things can have 'gotten out of hand' with someone, if you have never met.
I can't even see how you can be dating someone else, if you have never even met.
Maybe being not-very-computer-literate is making me naive, but my only advice can be ~ wait until you meet them & get to know them before dating them or proclaiming your love for them.
I know that Internet dating can work, because it has worked for other people, so I wish you well.
I still say beware & be careful.
Good luck.
