are we together or...

Okay so I have been taking to this guy since July maybe even June. we go to the same school and have the same friends. we started hanging out more and more recently and i am just so confused with what he wants. We have had conversations about going on dates and cute things but he never really makes an effort, some times he will be really cute and clingy and than sometimes he will leave me on delivered for like 5 hours. we’ve hooked up a few times and whenever we are with our friends he acts like my boyfriend (being affectionate, making out with me... etc). I just don’t understand what he wants out of what is going on. This is the first time I have ever felt connected and on the same level as someone. whenever we talk i feel appreciated and wanted, i have been able to tell him personal things that would usually make embarrassed or feel vulnerable. My best friends even say that whenever i am around him i seem so happy. I just feel like i keep getting mixed signals from him :/ help!
