Is he using me?

My boyfriend was recently with his baby mother at the hotel room. She was saying he bought her food, He paid for the room ( which he didn't) I did. Smh.. He's sneaking behind my back talking to her, using my car to pick her up still. She's always with someone's man. Then she'll say "oh, i didn't know those guys were with anyone because they lied" blah blah. 😒🙄now since im with him, he's blocked her number again. And as always, im the one paying for Hotel rooms, The Cars he's driving and he was just with another female a month ago. Probably 10+. When he's done using them , he wants to come back to me plus we don't ever use condoms even after finding out the baby mom is pregnant, we still don't use them. I don't know what to do. 🤦is he using me?
