What subjects/topics can you talk about with your boyfriend to have meaningful conversation?

What you want for your future is an excellent question to ask. Even though we don't have much control over what happens in the future, you can tell a lot about a person by their "plans" for it. For example...Do you want to go to college (assuming you're not in college right now.) Do you want to get married/have kids some day? It's important to ask those questions know instead of dating him for 5 or 6 years and then finding out he doesn't want kids or doesn't believe in marriage. I have always said until you know everything there is to know about someone, there is always SOMETHING to talk about. :)

You can talk about what your plans are for the future and his.  What you expect in your relationship.  What type of hobbies you both enjoy.  What type of entertainment you like and what fun things you like to do.  You can talk about your family the positive things.  Trips you have taken and trips you would like to take.  There are so many conversations you can have, just give it a little thought.  I hope this helps.  Take care
