Just because she is Muslim does not mean she is bad. She could be one of the nicest people on earth, but. Her religion is wrong, one of the wrongest on earth. (Is wrongest a word?) OK, maybe not on earth but just in the places it is at.
A Protestant and a Catholic can marry and it can work - as long as the Catholic side wins and the children are raised Catholic! I do not think a “Christian” and a Muslim can make a marraige work. The two religions are incompatable because ultimately, the Muslim side will not let the Christian side exist. I roomed with a Muslim for 5 years from Iran. Right after the hostages were freed too. Boy did we have some great conversations. I knew him and all his friends. Trust me, convert the girl to Christianity or just agree to be friends.
I stayed in touch with my old roomate for several years after we moved apart. Even after the Muslims destroyed his country, his friends were murdered in the Iraqi war or by the secret police. After years of his parents writting him NEVER to come home. He still hated the US and loved his religion. Brainwashing to the max.
If she won’t convert then don’t walk away - run for your life!
Sorry, I don’t think that’s what you wanted to hear but it is my “opinion” based on many years of life with Muslims.
If you pray, and I pray you do, then pray the rosary with great thought and meditation. Ask for the intercession of our Saints and Angels for you. Pray through the rosary and God will answer you. You just have to ask. Pray pray pray. Go to a chapel everyday or to a dark and quit place and pray for at least one hour a day, preferably through the rosary. Pray longer if you can. God answers prayer and His favorite is that with His mother, our rosary.
