I can’t type all have been through here cause it will take ages, on Monday here as a pregnant woman I woke being so weak and was craving for something to eat and this happened in way that if I don’t get that exact tin I will be feeling fainting or exusted so I called him and told but he said he can’t go to there are selling it bcus he was busy I could understand so I asked if I could go myself but he dint ansa me so towards 3pm or so I had to manage my self to the market to gut food stuff just to make sure there’s food at home wen he comes back bit while I was on my way wit son to the market his call came in and he where I was I told I was on my way to the market he said some one told him he saw me at one area like and I was like am just leaving the house to market so I ended the call I came back made the food he came started asking where I went? so told him that the question sounds like he trusted the friend word to mine so he told me that one day all this will end his just waiting for a proof to do what he want to do I left him to the room cause I already served his meal the nxt day in the evening after we spoke abt something he asked for my phone and stated dailing his friend number on my phone to know if I had the number so wen I came out to ask for my phone he that food that I was not the one that made it infact his been feeling uneasy that he has seen what he was looking for that I will see.
