Should I be worried ?

When my fiancé and I were first dating, he couldn’t keep his hands off me and even at 4am, he would wake me up to make love. Even period won’t stop him and I know it’s TMI. Recently,he went through a job changes and he hasn’t been the same since then. He hasn’t touched me for almost three months and we were supposed to get married in May 7th and he asked me to postpone it. I felt like he’s starting to loose feelings and when I talked to him about how I feel, he always shut me down and told me he wanted to get his life together first since he had too much on his mind. Should I give him more time? What if we never end up being intimate again? I am scared to lose him and missed how he was before. What should I do ladies?
