Is he using me?

Bf came to see me tonight, he knows am traveling after 2 days to visit my family for 2 months..

He had sex with me, then he wanted to leave! He didn’t even spend 3 hours! I was like WTF.. then he’s like okay I’ll stay more.. he stayed another 2 hours.. but I can feel that he wanted to leave, I told him if u wanna leave than leave... I said it in a nice way coz honestly I don’t like to feel that am forcing him..

I swear the first minute I saw him, I knew he’s only coming for sex...I felt the vibes. His body language it’s like he’s coming for a mission..

Should I leave him? So many other red flags..
