Confusion and fear

From childhood i always thought that marriage is very beautiful ceremony where two souls meet with each other. when i decided to get married i was really happy and he is indeed very mature and good but i don't know as time passed and the date was getting closer i loosed interest in all of the things and eventually i stopped talking with him. i thought after getting married and after spending time together the situation will get better and its getting worsened day by day as i have already loose interest from everything and currently i am confused with everything....
