Now my hand is going to be forced and I will have to be baptized by the end of the year. My gf wants my decision very soon
just the fact that you are on this forum tells me you shouldn't be baptized.
and the wording you used in your comments cements it.
what is the worst that could happen if you waited 6 months, 1 year, etc.?
i'm pretty sure you love your girl friend...that's not the issue here. (although she may say otherwise)
don't jump into a life changing decision without all the facts. do some more research and find out what it means to be a baptized jehovah's witness.
if you get baptized to make someone else happy you have made the wrong decision.
