New guy & mixed signals. HELP

I recently got out of a very serious two year relationship...and have been “testing the waters” and I’ve met this guy who has made me feel so many new feelings (I LOVE IT). He has very serious/dangerous job, and works 12 hours a day so we don’t text much and we RARELY get to see each other...but when we do I have an amazing time! He’s the quiet type...he never has much to say..so that’s taking some getting use to.. the last time we hung out we made out, then gave each other oral, and he fingered me.. well, over an hour had passed since I gave him head, but he wouldn’t kiss me goodbye!? Am I the only one that thinks that’s weird??? Since that night he texts me even less than usual and he doesn’t send hot/sexy things anymore...but he still wants me to come over Friday because he’ll have the house to himself....

I told him I felt like he was using me for sex and he reassured me he wasn’t...and said when I came over we would just cuddle and hang out and promised we wouldn’t do anything unless I wanted too....

BUTTTT, I still feel like maybe he wants me for sex? Just because he seems sooo uninterested in me :( I like him a lot.

What do you think?
