Humanities Homework Help

Hello! I’m working on a research project for my Developmental Psychology course and my study/topic is romantic relationships. For this project I will be separately interviewing 3 different couples that range in different ages. My first couple is in their early 20’s, second couple in their late 30’s-early 40’s and my last couple is in their late 50’s-early 60’s. What I need help and assistance in is coming up with and deciding what questions to use in the interviews with these couples, THATS IT! Attached I have my research proposal that way you have a further understanding of my purpose for this project. Please let me know if you have any questions, thank you!
