Dudess, there is nothing wrong with sharing your emotions and feelings when you're in a loving, caring, intimate relationship with your significant other. Attempting to do these things with a WAS will only drive them away further.
I definitely have the "cojones" to admit to having vulnerable feelings but I would never communicate these feelings to a WAS who doesn't want anything to do with me. What would that gain when that WAS is effectively communicating that they want nothing to do with you and are actively involved with someone else?
If my direct approach hurt your feelings FKAF, I apologize.
I personally believe that people need a dose of reality in these situations, I'm not going to lie to someone and tell them to do something when I think it's the wrong thing to do.
