Getting married is easy, staying married is tough and is not for the timid. You are very new in your marriage and have discovered that you are no longer happy. You should still be getting to know each other and enjoying sex and life together. What changed? Where did the joy go?
You need to get to a relationship counselor as soon as possible if you want to save your marriage. Be thankful that you don't have children involved. If you want to work it out it can be but, there is going to have to be an agreement from both of you concerning what you expect your life together to be.

Maybe your husband needs a second part time job to help pay the bills. Do you both work? Money problems and infidelity are the two biggest causes of divorce. You both need to be honest in where you want your relationship to go and how you plan to get there.

Please, if you want to grow old together, get counsel.

Good luck to you in the future.

Married to the same woman for 35+ years.
