How do I get help? 😔

I am a Christian woman and have been married to a Christian man for 8 years, we have two young children. We go to church every Sunday and midweek service. Anyone looking in would think we have it made. 
But it's not true. I feel like such a fake! Because our marriage is falling apart. I don't want to get into particulars. But it's like my husband has just tuned out of our relationship and family. I don't know how to fix it! I've tried everything I know, I love him. I know we probably need counseling but my husband will not consider it. I don't have anyone to turn to because I'm afraid of letting them down. Although my mom is beginning to notice things aren't right. Others look at us as a "perfect Christian example". I'm afraid of anyone finding out the real truth because I wouldn't want to hurt my witness to others. So I just keep it inside but i feel like it's destroying me. Besides praying, what should I do? Does anyone have some Bible based advice for me? 😭
Thank you ladies for your good advice! :)
With the Lord's help anything is possible! 💕
