There is a difference between Hajj and Umrah . Hajj is obligatory once in life while Umrah is recommended.
If Hajj has become obligatory on you (i.e. you are able financially and physically to perform Hajj) then it is obligatory on you to perform Hajj same year with out any delay even if your husband is not willing to perform it now. You will not be allowed to postpone performing Hajj because of your husband or any other reason as Hajj is Obligatory on you. You can join any trusted group of Hajj and go with them.
If our husband does not allow you to go for Umrah, you should obey him because Umrah is not obligatory but Mustahab (Recommended).
