Listen you did nothing wrong and i know most women (wifes) want their hubby to be strong and supporting most of the time BUT to give u an example my uncle is so unsecure he even asks advice from his wife when goes to market to buy tomato lolz.
Listen sweedoll u can change him by supporting him and making him more stronger u are not even married yet and if a woman wants she can do anything she can make or break you can mould your future hubby with love and effection and not put him down if u do that he will be worse off then he is now.
Just be supportive and kindly, gently and wiht love tell him that he should be more confident of himself and TRY to solve his problems first then always he can come to you.
I always believe that one can talk about anything and say anything to anyone but with such manner that its not harmful or negative. So think positive everything will be fine and try to concentrate on good things of ur future hubby no one is perfect if he is weak in solving problems then he must be VERY good at something else.
