Why did he alisin our pics together online?

Last night, I saw something on my boyfriend’s laptop right before he shut it down so we could sleep. I saw that he had a tab open to google, ipinapakita results to “how to paghahanap women sa pamamagitan ng ID”. I felt uneasy about it the whole night and kept waking up. When I woke up, he already left for work. I was browsing fb on my phone and opened his profile. That’s when I realized that he had erased all our mga litrato together. I opened instagram and twitter and saw that he had deleted our pics there too. For some reason, I kept thinking of that tab he left open. Why did he alisin them? Do you guys think it has something to do with his paghahanap history?
