How can I get her to take a bit more of the initiative?

Wait until she knows the city better. I find this same thing with men.

I know a man who answers questions with a question so you never know what he really wants.

Simple just ask her to plan a date for you guys, everything is up to her. I use to do this with my husband before we were married, then we just ended up taking turns to surprise each other on dates and secret places we where taking each other even if it was the park across the road for a romantic midnight picnic. Just sparks up the relationship.

After being in your situation I have begun to realise that in relationships there is usually a dominant person who takes this role. I'd say the only solution is too accept this. You might find that it would be worse to be arguing over what to do!

Just tell her that you are the one usually suggesting the places to meet and go and tell her its her chance you would like to know where she would really like to go or be or do and Thats your way of showing how much youc are for her Best of luck

best bet is to be completely honest with her, and tell her exactally what you just siad. You are very articulate, and I think if you say it in a caring manner, and let her know that you are addressing this b/c you actually deeply care for her and want a future with her to work, then it will be well recieved.

Tell her that you want her to decide where to go next time, and see what she decides. Maybe get her to give you some choices.

Just plain ask her to make an effort.

always ask her where she wants to go first...tell her you want her to be happy

Tell her how you feel... never hurts to be honest.
