You have no obligation to tell him your whereabouts or what you are doing.
This is a good opportunity to set a boundary. I just posted this to bustingout and it applies here.

What is a Boundary?
It is a property line that defines where I end and where you begin. Confusion in relationships often comes as a result of others’ not knowing where our boundaries are.
Healthy boundaries allow us to take ownership of what we are responsible for and to whom we are responsible. They provide a structure for balance and success in life and work. When we are free to set limits without guilt; we are also free to love without resentment.
Setting boundaries is not a means of an end to relationship. It is the means to laying the groundwork for improving relationships. Limits draw a line of respect. Without respect, love begins to erode.
Achieving a healthy life balance requires us to establish personal boundaries around the things we value in our lives. Modeling this behavior and respecting it in others will go a long way in developing authentic and lasting relationships.
He is attempting to control you. His behavior is like a child who doesn't get his way and then throws a tantrum.
Let him know that you don't appreciate the way he is treating you and you will not tolerate it. Then when he tries to cross the line, act on it.
He won't like it, but there isn't a way around it. Protect yourself.
