is it must to have as life partner why?

I dont think that life partner is inevitable in your life. However, if someone becomes and integral part of your life, thats a different story altogether.

Without a partner in life, life is meaningless. Either a woman, or God(become a monk), but you must have a partner. If not you'll miss out on lots of things in life.

Well yes it is. You cannot be totally independent man is a social Animal and communicate is totally innate for him At a part of life he does require to share things with someone, express, get love, be loved SO yes a partner is neccessary You do require support, no! People might leave you and yes you will come across new ones But life is all about stability and yes you do want to find a partner who is there for you under any circumstances

i helps very much

Yea I think it's a must, but not too soon. We need to grow and learn before we settle for a life with someone. I think it would get lonely to grow old all alone and never have someone to share your life with.
