This boy I like always says that he wants to talk to me and stuff, but when we do message each other (he lives abroad), it's always me asking the questions. He doesn't make any effort to ask me any other questions except what I'm doing and how I am. He just sends me loads of love hearts, and if I don't reply then he will send them until I do. I really like him but I don't know what to do because I'm getting very mixed signals

What should I do?
