Help 😩

So I’ve been talking to this guy I really like since May although we are not boyfriend & girl friend I really like him a lot he says the feeling is mutual & that he really loves me & mean it well yesterday I ended calling this because I was a bit concern why she was always posting on his Facebook & reacting to it so I call the girl & question her about him she gives me a little information about him so after we hung up I text him telling him everything the girl was saying he text back saying she is lying & he will prove it so he called me told me that put my phone on mute the whole time she lied about everything she was telling me so after that he said see I’m just trying to prove my innocents to you ... but I’m confused if we are not boyfriend & girlfriend way did he go out is way to prove to me o really like him a lot but sometimes I hear someone many rumors about him till the point I threaten to leave him alone then he would be like stop talking crazy I just can’t explain the situation do he really likes me or what
