Well, if you are a smart man you will take the majority of these postings to heart. I read one place that you said it makes you depressed sometimes, all of this...religion....I GUARANTEE YOU that Depression will be a Big part of your daily life if you let your Girlfriend drag you into this.
You can say it is your choice, but it is obvious that you are afraid of losing her.
If GOD intended for this relationship, it will happen. I say, 2 years is a better length of time to go with anybody before making any major commitment, such as marriage. You have dated her one year, you said....and she is influencing you into a "marriage" INTO the JW belief system.
TAKE another year; put your foot down. NO, put TWO feet down and don't let her step on them. Take charge and tell her you need another year to look into it.....THEN, Run like Hell.
Sorry for the bluntness, but sometimes it is the best approach.
