Chiibaby, thanks for your comment. You're right he could look for a job while I was pregnant but I think he just can't handle the thought of it at the moment because of the stress from his current job.
I ended up getting upset today, it wasn't just about the baby thing I've just been really sad all week about everything including him being so unhappy in his job and all his drinking. I mentioned the baby thing but he said he didn't think we should talk about it then because he had a hangover and I was so upset. I mentioned about me going back on the pill as long as it can happen in future some time and he said maybe but well talk about it tomorrow. I doubt we will though.
He must know the risks!
