For all things does matthew underwood have a girlfriend
First try to understand her, and then ask relative questions to support her feelings. After you ask questions about her, talk about yourself, how she feels about you?. 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 reflect if she is materialistic or really loves you. It is good to know about her friends to determine her liking and disliking.
