I think I read a post of yours earlier. You said that your husband is a pain killer addict, correct?
Definitely do not get involved with a man who is married because that is obviously not a healthy man! You need to work on you and if that means getting out of what you are in so you can find the happiness you deserve within yourself then you should do just that. Addicts will never be emotionally available and it is sad and it hurts but why should it hurt us if they are numb to us anyways? I hope you find answers and peace within those answers.
