First time sex FWB

I'm 16 years old and so is he. We had sex this morning and I heard him say I love you during it all. I didn't think anything of it and didn't want to ask during the act. He told me the reason he couldn't date me was because he liked a girl in Missouri which Is where he used to live. Should I ask him what he meant by that? And also how do I ask him what we are cause Idk if we are FWB or not cause a e've sexted before and sent pictures.
