Most Helpful Guy
I've been in 2 of them and in my experience their success depends entirely upon the people in them and how much effort they are putting into making it actually work and how much they want it, a couple things are vital for it to work though and that is communication, trust and making an effort to see each other. And ehh an open relationship no offense is not a relationship it's pretty much just friends with benefits and if it's open then trust is going to be really hard to achieve.
And I don't know if it helps or not but in all the long distance relationships I've been in, the distance was never actually the reason why things ended, but anyway just remember they are hard but not impossible.

if you're asking if that relationship will last, then you need to meet him personally first. It's so much different talking to him in the net than in person. You have a long way to go. Love has different facades, and I think you've just reached 1/5 in understanding love. You'll get to know the rest once you've meet him and be with him for years.
But if you remain having long distance relationship, then it's a decision that both of you should take. It's a combined effort to keep that relationship. Keep it if it's worth it. Again, it's a decision that both of you should decide. If one gets tired, the other one should catch. It's normal to get tired.
