Recently I have discovered that my partner seems obsessed with his cell. After receiving hefty phone bills twice in a row, I decided to go into the service provider web and look at the itemised billing. Here I have discovered that he was constantly phoning another woman and also sms'ing her realy often. When I confronted him, he said that it was a old friend from the past and they were just catching up on old times. Why only when I was not around? Early morning and late night when i was lying in bed sleeping next to him.(he claims that she missed called him and he just wanted to see what she wanted) He did not want to tell me he claims, because he knew I would over react! He did tell me that he ran into her at a shop - not that they exchanged cell no's. Then I saw a message on his phone from her - I did not freak, just asked him who it was(it was one of those friendship poems) He explained then, but only yesterday I realised how many times they were catching up! Then also on this bill, I came across some of these sex line no's!!! He claims that he was only curious! For 11 minutes? on numerous occasions? Our sex life is good, so it is not like i am withholding anything from him. Why is he doing this? He was unfaithfull with his partner before me, so does that mean that he will do it again? Please give me some answers!!
