Do you know for certain that your husband still loves you?  How can you be sure?  Is it because he tells you so?  Does that satisfy you or do you want more?  If you believe that he is detaching from you emotionally, you are not alone, but you can tell if he still loves you by analyzing his patterns of behavior.
The quantity of time that you have together is a great indicator of how much in love he is with you.
  There are obstacles in life that can eat up your time, like children, jobs, and bills.
  If he continues to make real attempts at spending time with you, take that as a positive omen.
  Should he create lame excuses to stay busy and therefore not spend time with you, that is a bad sign.
  Men who have emotionally checked out of the relationship will figure out ways to not spend time with you.
  They will watch TV even when there is nothing on or claim that they have to work all the time.
  If this is the case, you will need to attempt to fix the issues that you two are facing before time runs out.
When you ask your husband for help, is he happy to help you or does he ignore your request?  Does he make attempts to help you with chores to make your day a little easier or does he sit and watch you do everything?  Unfortunately, women who need to nag at their husbands to help with the housework; there is a need to be worried.
  However if your husband helps you and agrees to the chores that you ask him to do and occasionally take on all the house chores so that you can rest, you will not need to worry about how invested he is in the relationship.
