When they text you call you etc a lot that's what i did to my friends Edwin i would call him and text him all the time because i secretly liked him haha but later he asked me out so you know i stopped after that :D
Having spent a great deal of time away from my wife, any contact with her was key. When able, I called daily, wrote daily. Every day I let her know how much I loved her, & missed her. I set it up a schedule ahead of time with a florist so that every Friday she received flowers & written notes. I set up "dates" with her girl friends, to make sure she was okay and getting out of the house. Any RR available, I went home, anything to say I miss you '
