<human>: Give me a shortened version of the text

Today i was doing some editing stuff for my father on his laptop while he has was at work and had to register for something to get access to a certain plugin and so i checked his e-mail (gmail, which he never seem to be using, except for facebook and this apparently) and he had around 2500 unread e-mails, being the ggg i started deleting the unnecessary and countless facebook e-mail notices and then i stumbled upon alot of e-mails of notices from a dating site called zoosk. 

The e-mails were nothing personal, but there are several "search results" emails so it might be so that he was looking for women in the age of 40-50. While on the website i couldnt find any messages he send to other women or anything so i dont really know what to think of it but as this seems to be a "real" dating site unlike many fake sites it turned my stomach upside down, and i feel very betrayed somehow and disgusted. I don't think talking to someone that knows him would be very smart as it might change their opinion about him, even if its false, and so this seemed to be the only place to talk about it.

I'm really at a loss here, what should/can I do? My parents have been together for 20+ years and have been in a happy relationship as far as i've known..
<bot>: Was doing some work for my dad when i found out he is on a dating website looking for women around his age. There were no personal messages that he have send to other women. Feeling betrayed and sad, what to do?
