so me and my ex from last year are talking again and may get back together. I lost my virginity to him about 2 years ago and During our break up I had sex with another man. He has had sex with multiple females and only thinks I’m aware of one of them so he hasn’t “confirmed or told” me about these other females Bc he thinks I don’t know. I sometimes feel like I should tell him I had sex with another man but men take that hard and he didn’t tell me so do I have to tell him
