Just be careful, for your own sake and his. This sounds like a set up for emotional dependency on your end. You have to feel mentally and emotionally well & stable all on your own, and not because someone else makes you feel that way. I smell trouble with this, but it's your decision to date right after getting out of inpatient, which I think is against better judgement. But the point of your post was about disclosure. I do hope you disclose the full truth sooner than later.
