@Jojo, I have been reading about your fears, and much of them seem to be unfounded. Threats are just that, idle (in this case). I am not sure if you're reading what experienced members are recommending. Some of your fear appears to be self-inflicted (if real at all). You came here for guidance, and when you receive it, you keep asking identical advice.
Dr. Mohammed is a scam. He will never be able to harm you, nor anyone you care for. I did a bit of research... This Jessica person posted several times (the very same message) within a short period on several sites. All within a week.
"Hey,I'm so excited my broken Marriage has been restored & my husband is back after he left me and our 2 kids for another woman. After 8 years of marriage, me and my husband has been into one quarrel or the other until he finally left me and moved to California to be with another woman. i felt my life was over and my kids thought they would never see their father again. i tried to be strong just for the kids but i could not control the pains that torments my heart, my heart was filled with sorrows and pains because i was really in love with my husband. Every day and night i think of him and always wish he would come back to me, I was really upset and i needed help, so i searched for help online and I came across a website that suggested that Dr Mohammed can help get ex back fast. So, I felt I should give him a try. I contacted him and he told me what to do and i did it then he did a (Love spell) for me. 28 hours later, my husband really called me and told me that he miss me and the kids so much, So Amazing!! So that was how he came back that same day,with lots of love and joy,and he apologized for his mistake,and for the pain he caused me and the kids. Then from that day,our Marriage was now stronger than how it were before,All thanks to Dr Mohammed. he is so powerful and i decided to share my story on the internet that Dr Mohammed real and powerful spell caster who i will always pray to live long to help his children in the time of trouble, if you are here and you need your Ex back or your husband moved to another woman, do not cry anymore, contact this powerful spell caster now.
