<human>: Can you give me a shortened version of the text?

So girlfriend(22f) was out on girls night...we use her laptop for streaming movies and im not going to lie, i(26m) started snooping around in her 'pictures' folder. Mostly pictures of her and friends but one folder contained pictures of her and her ex making out.there were alot of them. They are ancient history but it bothers me immensely and its my own fault because i was snooping when i have no reason too. What the fuck do i do. Girlfriend came home and asked immediately what was wrong because somehow she could tell i was upset. I lied and said nothing was wrong. 

This is bothering me way more then it should right?. It still upsets me half a day later.
