Where to learn more on questions for your girlfriend
Ask about her, what she likes or dislikes, her childhood memories, her fears, her passion, her embarrassing experiences of life etc. When she talks, be a part of the conversation by asking random questions to make her feel that you are interested in her thoughts and feelings. However, don't be judgmental about anything as it is the last thing the woman will be accepting from you. Make her feel comfortable, and try to find out reasons for her actions and reactions. It is also good to ask her about yourself and how she looks you in her life.
