Should a third person be brought into the relationship??

Those never work in the long run. People are too selfish and jealous for three way love triangles to ever work.

I think it depends on the couple. Most people would say no. Some people would say yes. It's happening a lot these days. If the couple wants to do this in order to have fun with no strings, I can't judge them for their life styles.If a couple is doing it thinking it will build their relationship, that's wrong. You have to already know it's solid before doing anything like that. I have friends who are very close and don't go out looking. But if the situation arises, they might or might not join a third party. To each their own, I guess.

Its depand on couple many obstacles are in couples life but its depand on how to take it???

third person enter in a relationship only if he/she allows.wid my experience i say that wen the relationship begns to loose its "fire" people tend to look outside of their relationship... as a result a third person enters...its actually the fault of both the partners becoz the responsibility of a relationship enteirly depends on both the person.. some react to the third person violently some give neutral while some give a positive look...i think both the partner shud sit and know wat went wrong in their relationship. and if they can trust each other like they did before the third person enterin then they shud give a try to their relationship if they cant take tat they partner had cheated them then they shud let go the relationship... in most of the case people stick to their partner bcoz they think tat they lov their partner but thay shud understand tat a long relationship doee not require only lov but also trust...
