I rarely come on here anymore (just too busy!), but I wanted to come and share a website with you that might be a helpful place for you!
It's called Unveiled Wife: http://unveiledwife.com/
It is a place for christian wives to find encouragement whether in struggling marriages, or just want to improve. Go and check it out! Read the bio from the woman who started it. She is so open and honest about her struggles and how it lead to her ministry in this website. It has been a great place for me personally and the forum is a great place as well!
