This is an excellent post. I hope he will follow your advice.This is the most sound advice on this thread, imho ( even though he told you to run a little later )
This thread has been troubling me, so I spent some time in prayer earlier, to help me know how to respond. The Lord reminded me, that I do not know your fiancťe, all I have is what you've told me here. Now I'm not saying that you haven't spoken the truth or anything, but we must remember that this is only one side of the story. I can only see this story from one angle, and so I cannot clearly see what's going on. It's easy for us to respond to your situation based on our own relational experiences, but none of our relationships are your relationship. I don't know your past, I don't know hers. I don't know what causes her to be the person she is, nor you the person you are. I don't know how much she loves you, or how much you love her, words just don't express these things well. You said her relationship with God is good, and I praise God. I hear that yours is not so good, well a godly married is based on both parties having a close relationship with God. That should be some thing you spend time working on!
Basically. my friend, we're strangers to you, so please take what is said with that in mind. Asses this situation yourself, pray about it. Seriously, seek God, for He knows if she is the one for you. She might have to learn things, and grow more into the person God created her to be. You might have to do the same, whatever the case, don't through 8 years away, on the advice of strangers. She is hurt, and so are you, there needs to be a period of silence/separation, where you both can heal and pray, apart from one another. Let the Lord lead you, and her, and if it be His will, this difficult time, will soon become a thing of the past. If you both shouldn't be together, I'm sure the Lord will make that clear, to both of you. Just my humble opinion.
Praying for you both
