I've been in a relationship now for 4 years, a while ago another person kissed me and I went along with it a very drunken mistake. For the last 4 years I have lived with guilt every single day it has crossed my mind, I've been physically sick suffered attacks of panic. My partner has questioned me about it for the whole of r 4 ye relationship and I have been petrified to admit I've cheated. We have lived together a long time and we now have a baby together. The baby is my absolute world he is absolutely amazing and so clingy to me altho now 9 months old I will not let him be separated from me we spend everyday together. A couple of days ago my partner said he can't get it out of his head that I had cheated on him and he made me swear on my little boys life and I did in the middle of the argument without even thinking. After that split second of madness I felt physically sick that I said that and felt like an absolute vile human being knowing that I lied to such an extent. I haven't ate for days and feel physically sick that something bad is going to happen to my child I'm shaking writing this message. I know I'm a terrible person and going to sicken anyone who reads this. I'm desperate to take back what I said but obviously I can't. I'm a physical wreck at the moment Incase anything happens to my baby.
