Hook up leads to more??

Im in desperate need of advice. I met this guy on tinder and he was leading in towards hook up. I️ didnt intend for I️t to happen but we ended up meeting up and hooking up. We got to know each other and had some intimate moments. The thing is before I️t happened he would talk to me nonstop and now he’s barely texting me. Im legit obsessing over here and missing him. I know he basically got what he wanted but Im not sure what to do now.... I want to try to make I️t work If its possible....
