My boyfriend is a driver, and he often doesn't have time to talk to me or return his messages.

Then you should call him at noon and evening. Since you love him so much, you should let him know and let him tidy up. Maybe he is really busy. I am also a driver. I also drive. I hate texting while driving. You might as well call. 1 Naively tired. The most important thing for drivers is to have a good rest. At the same time, you should be considerate of him!
