I will use the illustration of a Tennis Match...
When I show an interest, Its like a serve. I want to have a return, so that we can get a volley going.
When I show and interest and don't get a return, I'll give the benefit of the doubt and show another. If this continues, then I will stop showing interest.
A volley is like a relationship and when there is no volley, I feel like I'm dragging a relationship by the hair.
Example, a nurse friend of mine works at a Hospital. I bring her coffee and hang out with her during her midnight meal shift. I ask her out, the next time I'm in when I bring her dinner during her meal time. She says she's busy, so I work with it. I bring more coffee, treats, etc. Everyone on her floor thinks I'm awesome. We go out to breakfast once because I caught her right at the most opportune time. We laugh have fun, but no plans are made. A few more trips go by and still not really getting anywhere. So I stop. A week goes by and she sends me a :-( face text. "Miss you." 3 weeks later, she is all bent out of shape because I didn't keep pursuing her and she talks about how much she liked me and what an awesome couple we would have been, if only I kept trying.
Contrast that with...
I meet a receptionist at a hospital. I think she is charming and stuff, so I bring her a coffee and a breakfasty type thing the next time I'm in. On my way out the door she gives me a hug and slips me her phone number. I call her Friday and on Saturday we go to lunch at Joe's Crab Shack. We sit on the deck and make fun of people as they walk by. Monday comes and she sends flowers to my work(At the time I was at a reception desk at a Naval hospital in Georgia) Tuesday night I get off work and pick her up, we drive for 2 hours to a Waffle House in the middle of nowhere, get milkshakes and come back at like 4am, so that neither of us are late for work. That Saturday, she wakes me up to go running at like 5am, then its off the breakfast and then the beach. We go to the Russian Orthodox service Sunday catch church and then go see a movie. And it snowballed from there, Football games, Huge Road Trips, Family introductions, etc.
I don't want people to change after they get married. I just don't like all the games that some women play before it even gets close to that point. We are in it together, it doesn't have to be difficult.
