First of all, they should have been upfront in the beginning. I feel like sometimes facilities will tell people anything sometimes to get them in the door.
Now to play devil's advocate, people will often come up with every excuse in the book on why they can't go to rehab. Work, having a dog, whatever. I did it too. I refused to do inpatient because I thought there was too much going on at work so I did outpatient and relapsed. Finally I realized that if I didn't get my **** together and make my sobriety the number one priority then I wasn't going to last. I LOVED inpatient and am sooooo glad I did it. Gave a full 24/7 recovery environment and better opportunity for building a sober support system. This is just my experience, probably not the same for everyone. Just saying that I can see why they would be pushing for it. They've seen people come and go and have a pretty good idea of how patient's impressions change once they're in the program.
