Married ?

Is it true that marriage can change people life ? Maybe in a way, yeah.
I read my friends' blog last night, they just got married not so long ago, and I envy their beautiful soul, u know... they have became mature and wiser on perceiving this life. I believe that marriage is good well therefore it's becomes an obligation for moslem. Telling u the truth I definitely not that married type of woman, I think about it a lot yes, but not to go to that direction yet how to avoid that and find the perfect justification. I don't see the idea of living together with same person for the rest of my life is suit to me... not that I am not loyal, d'oh! It's just the willingness to share, to tolerate, to dedicate... and so forth and so on just makes me hard to breath, seriously. Maybe something wrong with me but... that's how it is.
I was thinking to get married at the soonest last night, and... I was stressed and freaked out! it's not that I don't believe in my partner, I do believe him so much that he'll bring such a joyful life to me... I don't believe in my self that's the thing! I'm totally screw! Gosh, I am twenty something and having this life crisis! Anyone, do you know how to beat this paranoid ? I want to move on with my life... u know the thing with "the rest of your life" is stressing me out!!! How do these people easily decided to get married? oh My... Help me!
