I’m on a mission

So. I started seeing this guy. He’s cute, sweet, pretty lovely overall. I ask him a lot of questions to determine what he’s looking for. Are you looking for something serious? Are you interested in a relationship? He takes me down the garden path with yes for 2 months. We go out on a date. It’s lovely. The next day I don’t hear from him so I call him. He said hey actually what you said kind of freaked me out (I think I asked about our relationship status) he says I’m not looking for anything serious. I’m a chill girl! I said alright no problem. I had follow up questions aka did you want it and changed your mind, did I do something wrong, or did you always feel this way? He said he always felt that way. Then I feel like a goon bc why did you just not tell me that lol. Anyways now I hang out with him once a week and we have great sex and he treats me like a gf and I love it BUT THIS FEELS UNHEALTHY. Should I end it?
