Has anyone else booked their wedding for nearly 2 years away and keep changing their mind on things? Or have doubts about things? (I.e venue they’ve booked, car they’ve booked, dress they’ve bought etc etc) I keep doubting the choices I’ve made.. (well ‘we’ve made, but more me as he wants me to have whatever I want most of the time) I just need someone to tell me I’m not the only one! I think I’m going crazy here..
