A girl with a boy dilemma

I have a friend, not a close friend. I had a hook up with this guy at the end of may, we send each other snaps and talk when we run into each other. Almost two weeks ago he invited me home to hook up again and have been sending some naughty pictures, he also sent some two days ago.

Let's just say he's been sending signals that he's single and just wants to have fun, just like me.

Then i wake up today to find out that he has deleted me as a friend on snap and I hear him why on messenger.. He writes he has started seeing someone and she didn't like that he text or snaps with me, so it was the only way.

We have been texting and flirting with each other for a while until this comes out of the blue. I have some feelings for him, he is a great guy. What should i do?
