Keep on praying with all your might and hold strong on the gap for him. Never accuse him, nor argue with him, just pray that God will teach you to love him as Jesus loves us unconditionally. In the time being use this time in your life to get closer to God, allow God to be your all over your husband, and learn to rejoice in serving and praising God. Ask God to teach you how to show Jesus love through you toward him. Always look your best so your husband become attractive to you again. If you have to lose some weight do so, and don't let him see you looking gloomy, but always look cheerful even if you don't feel like it. Always keep your home clean and neat, so when he comes home he will feel more comfortable than in any other place. Learn to make good dishes for dinner so he will love your cooking better than anyone else's. We sometimes forget once we get married that there are so many competitors out there, and we have to keep on trying to impress our husband, same goes for men with their wives.
I have prayed for your and your for husband in agreement with you. Rest assured He has heard your prayers, and as long as you hold on strong and believe it will come to past you will be alright.
