Please, please try to relax. Much of what you seem to be experiencing is associative guilt related to the fact that you slept with someone other than your girlfriend, you allowed yourself to get into a situation in which you did have control and that you are utilizing the internet to drive you nuts.
Listen to what people here are telling you. THe three to six months rule seems to be fairly standard. However, the likelihood of contracting HIV under the circumstances you mentioned seem fairly remote. However, just because you had unprotected sex with a woman who has four children (is she married to the same man as the one who fathered her children?), are heterosexual, and live in the UK does not preclude you from being vulnerable to HIV. You could have been less fortunate to have had a one night stand with someone who was HIV positive, have been a heterosexual liaison, and still lived in the UK and have something serious to worry about. Please, in the future, let your head and heart lead you and not the booze and your ---- (you know what).
