Kim,

You are welcome to come to the Catholic Church. Your history does not show that you are currently a Catholic (If you are then please clarify that).

I would say, call your local Catholic Church and ask to speak to the priest. It is best if you make an appointment. Tell the priest your story and judging by what you have written he will probably give you information about what it means to be a Catholic and how one joins the Church.

If you do decide to join the Church the status of your current marriage of 16 years needs to be figured out. Basically, what will happen is that the first abusive marriage needs to be investigated and declared invalid.

Don't worry about the details, what is first and foremost is that God is calling you in a special way right now and when God calls it is always to something good.

Make that appointment and see what God has in store for you.

Fr. Jonathan
