My partner was following women on instagram and Tiktok and I found out. They were posing in underwear and he says he doeesnt know how he came to be following them, haha. He deleted them but I also found out he'd been liking a womans photos on facebook that were selfies of only her but he never added me on facebook or liked any of my pics. We have been together 17 years and he also is secretive with his phone. Am I being insecure?
