Cyberstalking and dating

I've pretty much cyberstalked everyone I've dated at some point. Why? Its fun... its not like real stalking where you can arrested...it seems like harmless fun. Or is it? I've broken up with two guys because I've caught them logging onto "date sites" while we were dating. I took this to mean they just weren't into me. Is this the right thing to do?

third date down... fuck this shit

I decided to get the third one out of the way. The date itself actually went well... interesting guy etc... we got along well. So then two weeks later he goes MIA. I only text messaged him once to see what was up. Then I decided to send him one message on the site and he deleted his profile like one hour after I sent the message. Apparently I'm a psycho stalker who needs to get blocked or causes people to completely delete their profiles. Wtf?? I think with the first on,(who I had no intention of contacting) I'm thinking he is the love and leave them type. I'm trying to figure out the second one but why would you delete a profile as opposed to blocking someone. Maybe I drove him to say "Fuck this shit! I'm done with internet dating".
Its the messages I get on their on a daily basis that I find amusing. Or reading peoples profiles and the forums where people relate their experiences. They are so funny. One lady said that she didn't want to sleep with a guy because she had genital herpes. She didn't tell him why and then they rented a hotel room so they could get drunk and she wakes up next to two empty condom packages. Wow.... didn't see that one coming. Alcohol... hotel room... I'm thinking that isn't something you do if you don't want to get laid. Meet in a public place where there is no alcohol present.
I had a Nigerian looking fellow message me repeatedly. His profile said he almost made it to the NHL and was a doctor. He put his description as Caucasian with black hair. He is as white as Barack Obama.
And then there is the guys who want girls who are built for speed and then say they want a long term relationship. That cracked me up for a good half an hour. Long term as in as long as you don't get fat and I still enjoy fucking you.
I hate the 38 year old men that say they are undecided about children. If you don't know by that age there is no hope for you buddy. That is either a sign you are indecisive or immature.
Anyway just for fun... I suggest you go troll the site plentyoffish just to read some of the ridiculous stories and profiles... for fun. I get a good laugh out of it now and again.
