Boyfriend is busy working overtime. What can I do to make him think I care about him? What should I do if the text message says something?

First of all, make a phone call between noon and just after dinner in the evening to tell me what I did that day.

Secondly, surprise him occasionally, such as picking him up after work or making him a midnight snack at night.

Get together on weekends and do something intimate. All these can be done, which should be very touching. . .
