My ex baught me a car in full of 3200.00 as a gift for our anniversary. Both our names are on the title. Could he come back and take the car from me?

My ex baught me a car cash in hand of 3200.00 for an anniversary gift to me and my son. Both our names are on the title. He said if he wanted to be a complete jerk he could take the car from me bc he paid it in full and his name is also on the title. Is it true that in fact he can take the car from me? I also have texts stating where he gave it to me as a gift for me and my son after he broke up with me. Can he take it from me just bc he baught it and his name is on the title along with mine?
