what is ideal life for an relation ship

There is no such thing as ideal time for a relationship. It doesn't matter how long is your relationship, what counts is your love for each other. Along with other important factors relationship will stand the test of time.

If somebody wants only to collect gf or bf, they might as well set time when relationship should end. But for me, life of a relationship should not be set, because it would just depend. it will depend on many factors - love, trust, honesty, compatibility.

There should never be a "goal time" for a relationship to last. Each one is different. Different people have different dynamics. It may work out for only 60 days with one person but 60 years for another. I've only ever been in one relationship in my life. We're at 4 years now and getting married in 5 months.

really?Is it a little short?If you really care for someone,I think,you will find that it is not enough even more than 1 year.^^

there is no time in an relationship .see whatever think or believe strongly happen in our life the first time u were in relation u thought it to b upto 6 months .and later it happen with u for ever still u want to change because if once any impression is passed to our sub conscious through our brain by sugesstion it will b stored in it if we forget also the same thing happen still we change
