Can Sexual Sin Alter Who God Has Intended For You?

My name is Chelsi and I recently joined a ministry. This ministry is not your typical everyone is Jesus lovers and lived blameless lives. We all come from perverse lifestyles, drugs, gang violence etc. once in the ministry you go through steps that get your life right with God and they teach you the world and eventually you graduate and help minister and spread the gospel. While in this ministry I came across a guy who became interested in me. At first I was not for it. My answer was no because I wanted to focus on God and build my relationship with him. Over time however, I began to let my guard down because I thought God was telling me I needed to trust him and let him in. I struggled with typical "daddy issues" growing and have always had a misinterpreted idea of what a man was, his purpose, etc. This guy reveled to me that God had shown him I was his wife. Eventually I started to believe him and we started dating. We had lots of boundaries and did everything to keep our relationship a Godly relationship . (Mind you this ministry has a very strict policy on dating and we went through a very tedious process before we were given permission to even pursue one another). So I thought this was a God ordained relationship and felt as though I had not only the blessings of my leaders and mentors but Gods approval as well. We ended up falling months into our relationship and had sex. His view was I plan on marrying you anyway so I don't really think it's that wrong but he respected my decisions to remain abstinent until marriage. I know God forgives us of our sins and all but now I'm starting to question if this is really a God ordained relationship. I always prayed that my husband would put my salvation before his temptation and that's all I have ever prayed for . I don't know if I should cut off this relationship or try again and rebuild it and keep it pure and untainted. Can we destroy God's plans for us? Does He take away all that could have been ours when we choose otherwise? Does o
ur sin change the plans for our lives?

Thank you. It really is. It's the best thing that has ever happened to me. It's Eddie James Ministries btw. He is a really awesome man and soooooo sooo anointed. Do you believe that when you ask and pray for very specific things God will make sure he gives that to you? Ask and you shall be given is what the bible says.. But I've also been told God has three answers , "yes , no , and not yet." But yet He KNOWS the true desires of our heart how can He say no when we ask for these very specific things . ( and let's just say none of these things are bad , like drugs or greedy or anything )
