Well intentions may not always be correct

So how do you tell well intentioned people that they are doing more harm than good.  If you say it nicely they don't listen, I would imagine if you say it not nicely they would get hurt and offended.  They are so concerned that I do not date enough.  They keep asking me about it and pushing me to go to more singles activities.  I do not have the energy or motivation to try and meet and woo men right now.  If a man wants to ask me out on a date, then he has to make the effort because I am to exhausted to do the whole peacock dance anymore.
It begins: You dress up, do your hair nice when you know you are going to see him, you get twitterpated when he's around, you laugh and try to flirt with him, hoping he notices you.  It ends: eventually you wake up and realize he doesn't seem to see you in a dating sense, you are the little sister or the "friend". And that is all you will ever be to them. 
All I have gotten out of the dating world is continual broken hearts. I am not obsessing over being single so I don't know why people around me are.  I figure there are far worse things than being single the rest of my life. The more they talk the worse I feel.  I wonder what is wrong with me that I don't get asked out.  And the fact that they are all so concerned just makes me more concerned.
