Hi Deborah,
Have you researched the Trinity outside what appears in Watchtower literature? If not I recommend that you do. Most JWs know nothing about the Trinity beyond the Watchtower spin, which is dishonest, inaccurate and highly simplistic. If you do not know what ontology and economy mean or have not heard of Modalism than you are not yet in a position to make a judgement on the nature of God (no disrespect intended as possibly you are aware of these things.)
As a JW I prided myself on fighting Trinitarians (though never seemed to convince anyone at the doors that Arianism is correct) yet had never heard of Modality. It was only once I left that I found that Pentecostals are generally not Trinitarians but Modalists. How did I not know? Because the Watchtower library only mentions the word Modality once in over 50 years!
If you research without Watchtower blinkers you will find that the Trinity was created by people trying with utmost sincerity to unravel the mysteries of the Bible, and the JW Arian view becomes contradictory with just the slightest amount of research.
Another suggestion is to use other translations apart from the NWT. The Watchtower Bible is supremely dishonest in adding the word Jehovah to the New Testament, changing the intended meaning of key passages (see http://www.jwfacts.com/index_files/Jehovah.htm) and to obtain an accurate understanding requires comparing several versions.
