I need to know wether or not it would be allowed for me to marry someone.
I had been in a relationship with this girl for about 2years. The relationship ended just over 3months ago and since that moment i havent spoken to this girl. Allah (swt) has given me the blessing of turning strongly to Islam and I have learnt a lot about the mistakes I made and understand the need for my sincere repentence. The girl has since contacted me and even though I hesitated to respond I felt I needed to make dawat to her, I took the opportunity to enlighten her on what i had learnt and advised her to follow suit and repent strongly. She is complaining of depression and constant thoughts of me etc.. I have told her it is just the shaitan taking advantage of weakness in emaan and she needs to strengthen this by making acts of ibadah. However she did take the opportunity to ask me to consider her for marriage. I told her i cant marry her or anyone else in this situation and the most important thing for both of us right now is to repent and seek forgiveness for what we did and then think of marriage. I told her i wouldnt be responding to any further contact and that she shouldnt try and contact me again as it wouldnt be right.
Since then i have been bothered by thoughts of marrying her or not, no thoughts of contacting her or doing anything haram, just her proposal. I wanted to know what direction to take.
Am I allowed to make istikhara on it? And if I take the proper route of approaching her wali and proposing marriage would it be valid? Do we both need to go through a period of repentance beforehand or anything of the sort? Or is it strictly disallowed completely?
