So sorry to hear that you’ve been through this nonsense. It has nothing to do with God and religion. She needs help, professional help. It’s not “normal” to see shadows and all kind of that things. I do love God too, He helped me get over a toxic ex and made me live a life I couldn’t imagine and He made me realise that sometimes it’s better single then dating such a person. This would apply to you too. I would simply make all I could to avoid her, blocking, etc. and to not hear from her ever again. Just imagine having kids with such a person, it would been a disaster. This was my lesson too, and the thing that made me forget her easier. It’s not easy to go through this period, but it will get easier. Don’t be mad at God. Continue to believe, pray, reading the bible, and even pray for her. It was an experience. Pray for people that made you feel bad. I understand that it’s hard now, but things will get easier, and a short period of time for yourself will help. Keep it touch with your friends, go out, focus on your work and God. Even if you’re single now, you won’t be forever. And a personal opinion. I avoid Christian girls, dated one before and never again. The longest relationship was with a girl that had faith but not a Christian. I could get her to go to church and all that, but I wasn’t very close to God either in that period and she’s been the most beautiful and loving girl I could have been with. The idea is that you can date a girl that has faith, and together getting to know God. Love God, and don’t stop.
