M.L.
I wish every woman on Mamapedia could read your post. Your situation shows a good reason to remain 110% faithful to the person you marry, even before you take the vows. Once trust is broken, it seems almost impossible to repair completely! But I honor you for trying.
I recall an old, old illustration comparing the marriage bond to a fine porcelain teacup. Porcelain is beautiful, and it's a lot sturdier than it appears. But it can be broken. If it breaks, it is often possible to repair it. But the cup is never quite the same. It's not exactly the way it was before it was broken. Even if you might be able to use the cup again, you still know there are repaired places.
Of course you go through rough patches. So does everyone else. Sometimes you simply have to go day by day (hour by hour?). Did today go well? Then you can be thankful for a good day. You may not be able to trust tomorrow implicitly, but you're willing to go forth, work hard, and be honorable in the way you treat your husband. I know what it's like when every day is - well, a challenge to the mind! If you need a counselor to help you, go ahead and find a good one who will be part of your cheering section.
You also need to find some sort of sitter your husband can trust. Do you all go to church? Ask there for some names. Perhaps you want to try an older woman - one who will drive herself to your house and back home - if your husband has reservations about teenagers. Get at least five references for this person, and if all the references are outstanding, tell your husband he needs to try her out for forty-five minutes. Then you'll have to figure out where you can go in forty-five minutes - I was thinking of dinner, but that depends on the restaurant! You and your husband need to go out by yourselves once in a while, just the two of you. I think it will help the way you feel, because with your schedule you MUST need some recreation and renewal!
