He said he loves me....

After about three months, he told me that he was pretty sure he loved me. He kept saying it through the day/night we spent together and every rime i felt something warm inside my stomach. I’ve never been in love before or had anyone say it to me..... i’ve wished so badly for it. Y’all probably have all seen my posts on here. 😅 But anyways, when do you know when to say it back? I didn’t because i think i need more time and just need to reflect. I like and care about him so much.... but when i say it i want to be sure. When did you know you were sure??
