My not so expected life..

Finally this day has arrived.. Its my marriage today.. But there is always a huge difference between what we desire and what we actually get.. Maybe mine was unexpected..unrealistic and really the worst surprise a girl ever want! I know I am confusing everyone reading my story.. This is not like I have lost my love or I am marrying someone of not my choice.. I am.. But how can I be happy??

How do you feel when you have to share your husband to another girl? And when that girl is his ex and your ex bestfriend whom you hate the most??
