I'm not bashing catholics or any other denomination out there, but a part of me wants to think the reason why you are having doubts about whether or not you were really saved is partly because some people out there teach conditional security. (which means that you can lose your salvation after being saved). I vehemently disagree with this view. Now of course only God knows our hearts, but by just reading your post, and looking from all outward appearances, it seems to me that God is dealing with your heart on account of the sins you are in which you have openly shared to the forum. (ie: married to an unbeliever..etc.)
Hebrews 12:5-8
Now the situation you are apparently in demands a response from you. You either can repent from your sins and seek God's fellowship again and allow him to restore you, or you can continue living the way you are now and let things get worse. AND THEY WILL GET WORSE UNTIL YOU ALLOW GOD TO MAKE A CHANGE IN YOUR LIFE. How do you do that? Simply start being obedient to His Word (The Holy Bible). As far as the consequences of the sin you've been in, it may take time to heal from all of them. There may even be some that are permanent, but remember this: There is nothing that the Lord cannot fix and make right.
