@Candy: i got married last September & my DH also hasn't been to church with me. I only recently started going to church again...
Sometimes, when u feel overwhelmed or frustrated, it really helps to have a "greater spiritual belief/power" -whatever that may be, that you can turn to. it tends to give you hope, peace & a feeling that everything will be ok. It also tends to give you PERSPECTIVE and allows you to look at the bigger picture and not focus so much on the problem. I know it sounds airy fairy & trust me, I am no sunday school teacher or church-server and my attendance record at church is SHAMEFUL

but it has helped me to turn back to God...and maybe it can help you too.
Just remember "HE KNOWS THE PLANS HE HAS FOR YOU"...
& I recently saw some of what they call "prayer affirmations" and one that stuck in my mind was "I give thanks for the blessing in the problem, and the problem becomes a blessing..."
Good luck. I know how stressful wedding planning can be but remember that you will (hopefully0 only get married once and from time to time, you need to release the stress and ENJOY planning your wedding to the man you love. It is a joyous and beautiful thing.
