Is there a such thing as too agreeable?

I (25F) have been recently dating this guy (27M) over the last month. A few dates/hangouts - not officially in a relationship but I had thought we were heading there. That is…until he ended things last night, when I asked why he just said I was too agreeable for him.

I was kind of confused because I’ve always associated this term with people who are like..doormats? (If that makes sense). And I don’t view myself as such - I’m pretty outspoken about things I don’t like and have always been pretty good and standing strong on my boundaries.

When I ask for clarification he pointed to 2 specific events..

(1) Last week we were hanging out and decided to get dinner. He asked what I wanted and I was like I’m cool with whatever you want. He had laughed and said “Don’t say that or I’ll take you to get seafood or something.”

When we first started talking I did mention really not liking seafood but I took this as more of a playful tease and just laughed before following it up by saying if that was what he really wanted then I’m sure they have chicken tenders or something.

(2) He came over to my apartment after work 2 days ago; I was asking him about his day and he mentioned this project he’s working in. Our fields tend to have some crossover and so I was asking him a few related questions. And he snapped saying he really didn’t want to talk about work anymore. Which I didn’t think was unreasonable, since I’m the same way sometimes…and so I just said okay and changed the subject.

Maybe I am missing something or just viewed the conversations differently, but I hardly think I was being overly agreeable. Just realistically…understanding? I don’t know.

Anyways, I’m not particularly heartbroken over the actual guy but I’ve just been reflecting on what he said.

One of my co-workers said he was probably just making up an excuse instead of just saying he wasn’t interested anymore…which makes more sense to me.

But I guess I’m just curious if being “too agreeable” is an actual thing? And What does that actually look like? If there is, is there a way to avoid coming off as such?
