Emotional attachment after sex

I met this guy from OLD. Conversation was ok except he didn’t ask many questions as me. But we did chat everyday. We messaged for about a few days on the app and then he asked to exchange phone numbers.

After we started sexting, we chatted non stop from the morning till we went to bed. He shared his life and asked me about my day. However i pointed it out that he doesn’t ask many questions about me. Not sure if he is only interested in sex. He said he will ask more questions and told me not to take it as negative because he is sexually attracted to me. We met and ended up having sex on the first date. I know it’s not great. I think we both were too horny and haven’t had sex for a while. The sexting built up the hormones in our body.

After that, he became distant and didn’t text like before. I texted a few times and asked what’s going on. The answer was busy and everything was ok. So I stopped texting him. On the weekend he texted me and asked me to go to his place for a movie. It sounded like a booty call right? But I still went because I wanted to hang out with him. During the movie he put my hand on his pant, and I just played with it. We kissed a bit. This lasted about 2 hours. At the end of the movie, he said he thought we were going to fool around. I felt his disappointment and I left. Actually he told me to leave. I was upset the way how he treated me. I texted him my feelings and stopped talking to him.

Last weekend we matched on another app and he texted me, so we texted again. And he asked me if I want to FaceTime or go to his place. We ended up having sex at my place.

I told him I want LTR and he said we should hang out first and see how it develops. Clearly this guy is not looking for something serious with me. I feel we are heading to fwb or hookup relationship.

However I feel I am emotionally attached to him now after the sex. Can guys really separate sex from emotion, and treat it as a pure physical things ? My brain told me that I should stop seeing him and move on, because I deserve someone who treats me better. But my body is attracted to him and emotionally attached to him. I do enjoy the sex.

How can I get out of this situation? 1. Talk to him about the fwb arrangement? And then keep dating till I meet someone else? But what if my other dates find out ? I also don’t feel it right.
2. Talk to him if he wants a relationship. He probably will say yes to keep me for sex. He told me how much he likes my body and enjoys the sex. But I don’t feel his emotion. I think he probably lied about it .

Long story short : I met a guy 3 times and had sex twice. I am emotionally attached to him but I don’t feel the same way from him. I enjoy the sex with him but don’t see a future with him. Can I keep the sex without being emotionally attached so that I can keep looking for someone else ? Does it sound wrong? Or shall I just cut it off and move on ?
