You have done NOTHING wrong. Do not blame yourself for your partner’s actions. You have taken an incredibly brave step to do what is right for you and Nate.
Your partner is angry because of what he has done. Because of what gambling has done. Not because of what you have done. You were caring and loving and did everything right by him.
As far as i see it, what he is doing is manipulating you. He asked if he could come back, you had the control and didnt respond. Gambling loves to have the control so it tried to pull it back by telling you what you didnt want to hear…that he would leave and not come back.
If he has already come over to see his son do you really think that he wouldnt come back? Also, do you want him back in his current state, isnt that the whole reason you asked him to leave in the first place? Because you couldnt cope with the gambling anymore. Because it had exhausted you.
There is nothing wrong with taking a break from it all and doing what is right for you. You do not have an addiction. You love someone with an addiction.
Stay strong for you and for Nate and keep posting. We are listening.

p.s. I have done what you did. I have rang my CG over and over and over. I have done even more stupid ridiculous things for my CG than i care to think about. I recommend turning off your phone and do something positive with Nate and forget about gambling for a little while. It might not make you feel better but it will give you some moments when gambling doesnt take over your thoughts.
