Being FWB zoned?

Friend zoning?
So I met this guy a month ago. I'm 49 and he's 9 yrs older. We hit it off right away. He came on strong ... Saying he's crazy about me, thinks about me all the time, falling for me ... We have talked on phone and texted daily since meeting. Last Sunday we got intimate for first time ... Truthfully he wished for it to happen sooner but respected my wish to wait. Since then we still talk and text daily but no longer tells me he misses me or calls me names he did before (sweetie, babe, etc). He doesn't text anything sweet like he misses me ... If I text it first though, he will respond in like. About 10 days ago, when I thought he was losing interest, I told him (texted) ... He assumed I was trying to dump him and got upset so I don't want to say it again to him but I can't help but feeling like he just thinks of me as FWB now. We do have plans tomorrow and he's planning on staying overnight.

Just looking for thoughts. Does it sound like it will be over soon? Should I address it again? He does initiate phone calls and texting. He's also been under incredible stress at work (job on the line), planning a move, not sleeping much. Not sure if it's just that or ...

Why don't you just ask him what his expectations are? Do you want an exclusive relationship with him, or would an FWB situation work for you?

We already talked about being exclusive. He brought it up. I'm guessing he thought things were getting too serious so he's pulling back. Or he's planning on ending things in a few weeks, or sooner.

So his behavior changed after you slept with him? How long have you been exclusive? How long did you two wait before sleeping together?

Thanks for the advice. I addressed it ... Rather than just be honest, he dumped me stating he couldn't deal with my need for "affirmation" and he needs to be selfish and date a woman who is part of the solution rather than the problem. All through text mind you. Coward. Lesson learned: always trust my intuition.
I was slower to come around to his intense feelings and I guess once I did the challenge/fun was over.
