Am I a rebound?

Savannah 🌻
This guy I'm into atm was just recently broken up with by his girlfriend of 7+ months. According to him, they had taken a "break" about a month ago, but she broke up with him officially less than two weeks ago. He started texting me last week, and it had been a while since we last talked, but we've just been getting along really well. We hung out today & we kissed at the end of the night, and I think I might really be into him. I'm just worried I'm a rebound? I'm worried he's not really over his ex and he's just trying to get over her by jumping into a new relationship. I told him how I feel about everything, but he says he really does care about me and I'm not a rebound.. what do you ladies think?
