Out of my head on the topic of things to say to your girlfriend
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. You can also present some hypothetical scenarios, and ask her how would she feel if you react to some situations in a certain way, and if sometimes you don't have enough money to make both ends meet?. This will help you know about her nature, and if she truly loves you.
