Are long distance relationships worth it?

If you really love the person ofcourse its worth it. Trust is very important part of relationship. So doesnt metter if person is miles away, or in same city, if you have no trust thats not good. Edit: And I mean on relationship between two people that had to go live in other places at one point. Not the one that started online and dont even meet at all.

I tried such a relationship and it failed as expected.

Depends on how strong your relationship can go. I think that when a couple can withstand the test of distance then I guess that is doable. I have seen many who are like this.

It depends with both ends. They should have trust and understanding in everything

Yes, I don't believe too. That's because I had a boyfriend before working in Saudi. Then, came now my husband,

No.

It can work for some people. You should have trust, time, effort, etc And constant communication to make your relationship work.

It is worth it if the relationship works.
