help please

me and my ex just broke up not even a month ago...

well he’s already got a new girlfriend...

well he had his new girlfriend over last weekend and he snuck out and asked to see me. (she lives in a different state)

well we meet up and have sex....

well this weekend he texted me (girlfriend is back in her other state) and he says hey come over and spend the night....

well i spend more than just the night i’m there the whole weekend.... and we sleep together the whole time..

does that mean my ex still likes me. because now i’m confused when he has the chance to sleep with his new girlfriend he didn’t take it.

*update to this post he’s not dating her is what he told me. he’s been messing with other girls cause he’s single he told me. *
