Should i stay with my fiancee or break up our family?

[*KittyKat*]

before i got with my fiancee we dated other people, and he had a gf but i didnt have a bf because i didnt want one we have a baby togehter though. well some of the guys i met were nice and always gave me compliments and bought me stuff i admit i took advantage of them but it was just for fun they always took me out to dinner @ nice places and when we went to the mall they got me whatever i wanted and always took me to the movies and payed for everything for me even at the clubs they always bought me drinks because they liked me but i didnt like them, now that i have my fiancee i kinda miss all of that, he wants to get married next month but i dont want to, i miss my old life i miss the freedom i had. what should i do? i love him and dont want to hurt him and our baby loves him to death, we are also expecting our second child but i want to have my fun still
