I've been dating this guy for three months this week. We see each other and communicate pretty frequently. He attended my company holiday party with me this weekend and met my parents on the same evening. I've been feeling the need to have "the talk" but wanted to be very careful about how I approached the subject. It's been a while since I've asked if he's seeing anyone else so I asked again yesterday and he said occasionally. I also asked for the third time if he was sleeping with anyone else and he also answered occasionally. Thing is, the first two times I asked he said no. Why suddenly did he say yes? I don't know how to handle this situation. I'm not ok with sleeping with someone who's sleeping with other people and I'm also upset that he lied to me. He tried to play it off as if it was the first time I'd asked but we both knew it was bull. He also tried to be all affectionate but I wasn't feeling it. He said, okay you're mad at me now and I said yes, you lied to me. That was the end of that conversation and we pretty much drove in silence on the way to my house. I heard from him via text later in the afternoon. He said he felt bad and asked if he made me sad. I still haven't responded. I just don't understand why he met my parents or why he's making plans with me in the future. How much longer does he think that he can string more than one woman along. Any advice?
