Hi, when me and my x-girl met, i prayed over us, and we made a covenant with God, to say we will be an examplary Christian couple,and get married. Subsequently, i fell by the wayside, and she broke up with me. I have since repented from my "evil" ways, but she is finding it difficult to forgive me, and she is doubting that we are to be a married couple.Question,Should i forget the promises made in the presence of God at the beginning of this relationship?

Well you said she is "finding it difficult to forgive" so I would get on my knees & ask our father to guide you back into her arms if He indeed wants you to fulfill that vow. Any vow or covanant you make is very important to God that you fulfill your contract because God wants us to be people of our word; we are after all made in His image & His word is so powerful it makes the crooked things straight.
Now there is a passage in 1 Cor 7 or so that mentions that if the unbeliever departs you are not bound in these circumstances; but I doubt that would apply to you because you are the one to have backslided & repented over the matter (whatever it was) & so the issue isn't so much an unbeliever departing but rather someone running from possible future pain or jus the inability to forgive or forget or watever it takes it make the relationship work. Just do your best to fulfill your word & God will see the effort you make & He will make a note of it.

The Lord Reigns!!
Last week, i received an email from my x-girl, where she states she FORGIVES me, and we have started talking.
