Activity: call her at some point during the day and just say "I was thinking about you so I had to call and tell you that"
I called and got her voicemail so I left a message. I got a text back about 15 minutes later that said.. "Thanks for message. It gave me butterflies. I don't think you have ever called me and left me sweet message. I love you baby!", then she said "I am gonna save it and listen to it on bad days". So this one went over really well. Something as simple as a call out of the blue can mean alot to her. This really motivates me to keep it up.
