listening
offering to do things I want to do
genuinely asking me how my day went, how I am doing
putting me first
the old tradition gentelmenly things are nice; opening doors for example
doing things like chores and cooking as a way of sharing the load and not expecting me to do these things
asking how they can help
offering to include me if given social invitations (and not attending them if they clearly make me uncomfortable)
never making me second fiddle; never canceling our own plans to do something else
little terms of endearment
.... I could keep going here...
and, of course, telling me I am beautiful and he loves me every day.
