So sorry dear ...i had a similar case when with my ex well i served in his state of residence but we still have to travel to see each other, different local govt, we preferred it like that , yes we later parted ways mutually,there was no money to start settling down, and i was having plenty suitors and my family wasn't smiling ..well he begged me to move on and after dragging my feet for about another year , i moved on, yes am married now but i really do miss him and we both regret it till date, he told me he got his girl pregnant and just paid the bride price and things are getting better now, he still updates me even if i am not in Nigeria,so poster whether you lived with him or not, a cheater is a cheater and that wont stop him,if it was meant to be even if you like serve in zamfara he will be faithful to you, move on dear there is always a very bright light at the end of the tunnel its not your family and friends that will be in the marriage its you,the choice is yours to make, is he worth all the troubles. good luck.
