My advice to you would be pray for strength and try and find a support group that can support you emotionally through this time of finding yourself. You deserve much more that you are receiving its quiet easy to say walk out but actually doing it can be terrifying, but remembering our living God and submitting all your troubles unto Him will allow you to heal and find new strength. The relationship was meant to test you, use you and most importantly teach you. Out of this relationship you need to take all the life lessons with you. I pray that God will guide and protect you through this difficult time. Once you out don't forget to pray for your ex as the fight is not against flesh and blood but against the unseen spirits that seek only to destroy what is beautiful. All of the best and I will continue to pray with you and for you as I know exactly what it means to walk away and regain confidence to move forward.
