how can i get my husband to trust me again?

I have never cheated on him . And never will. My husband is a very jelouse guy and last weekend i was on facebook and someone a married guy whom me and my husband now from long time ago requested my friendship and i am sure he requested my husbands too just that he is not on there that often. His wife helped me out alot with my little one when my hubby was in iraqu but somehow we lost touch. I went on her husbands wall and in that moment my husband walks into the room and i clicked it away and he asked me what i was doing and i lyed to him that i was playing poker but he has seen the other mans picture. I did not talk to him all i was looking for was to see if his wife has a wall too cause i have searched for her before and there where alot of same names without profile picture. The reason why i lyed to him cause i knew he would get mad at me for looking at some other mans wall and of how jealouse he is and i got scared. Now he doesnt talk to me and only small talk just to see how the kids are doing. He told me i disgust him cause he would have never thought that of me. I have told him i never had any bad intentions by going on the other mans wall but he does not believe me cause i lyed right in his face. He works out of town and stays over there during the week and i have cought him texting other women and how she misses him. I never did this. I am just crushed and crying cause i know i didnt cheat and i wish i would have not lyed to him. How can i get him back?
