I agree with the above comments. You didn't do anything wrong by giving him cigarettes. Had you given him money that would be a different story cause then he could use it for more booze. And like mentioned above you didn't offer him a hot meal or a bed to lay his head on for the night. Don't feel bad I don't think your enabling him by giving him some cigs. And of course its going to be harder for you detach from your son then your ex. You gave him life, you felt him growing inside you for 9 months (if you went full term). So of course your going to have more of an attachment to him, it's only natural. I personally don't see anything wrong with what you did, so give yourself a break and stop beating yourself up over this. Try not to lose any sleep over this, we think your in the clear.
