What are the essential factors needed to sustain a long distance relation?

I have a successful long distance relationship with my partner, we've been through for almost 4 years. I am so blessed that I have found him. He is from Thailand and I am from Philippines but I can still feel that we are both attached to each other and we have a daughter that binds us, I love him so much and happy to be with him.

My first relationship is a long distance one. Well, it needs a lot of trust and assurance that both of you wouldn't cheat and betray each other's TRUST. There should always be OPEN COMMUNICATION and the couple needs to talk/text/chat often considering that they don't see each other. For my case, I haven't got the chance to see my him because I was studying at that time. But I already met him personally way back when we're still kids. Then we got separated for my family went somewhere to find greener pasture. I guess sometimes, it's not enough that in the course of such relationship couple just communicate online or through phone/text because based on my experience, you really need to have that time to be together even once or twice a year. Trust me, temptations will come one day, and couples should be very careful if they want the relationship to last. My relationship ended because someone caught his eye while I was away. But it didn't make me bitter, it helped me grew strong and learn the value of trust.

I think that the most important factor is mutual thrust. It's much harder to thrust your partner when he is milles away but you have to do it if you really want think to work out between the two of you. sure after you turn the computer off all kind of things might be going trough your mind : what would he be doing now? who is he with? but you have to chase tose questions away and thrust your partner.

In long distance relationship trust is required as well as strong character. However in my opinion only 1% of such relationships got chance to survive. I was in such relationship and it didn't sustain. I was focused on work and how makes everything work and the other person was focused on someone else.
