In what ways have you violated the agreement?
All of these things were done with the mother's consent, although if you cannot prove it, then you may have a difficult time.
You could lose joint custody, but prhaps you can think of ways you might be able to produce witnesses that the mother allowed you to do these things. The important thing is that you not miss any court dates and tell the absolute truth to the Judge. You will need an attorney if you can afford one. If not, in some states the courts will appoint an attorney for you in custody matters. Good luck!
