Is it a potential relationship deal-breaker if one party stutters?

Is it a potential relationship deal-breaker if one party stutters? Asking cause yeah I’m the party in this case. It’s tough being a man trying to find a woman as it is but the fact that I stutter makes it feel 100x harder I recently met a nice girl at work and we started talking. Found out we have lots of things incommon and always something to talk about, which she said as well so I don’t think it’s me misinterpreting things. I tend to start conversations more which is also challenging but I try. We text outside of work too but semi-frequently. We shared personal stuff about each other too and she was supportive and as I say, she generally very nice person. But recently I noticed she barely talks to me at work an even then it’s mostly about work stuff. When we text we have better convos so I’ve been wondering maybe it’s cause of my stutter? As to the potential relationship deal-breaker part, I’m wondering cause when we first started talking I felt she was more interested in me than she is now. Granted it doesn’t have to be due to stutter but it’s hard not thinking about it. Maybe I project some Sub-conscious insecurity? I’m always being myself and I don’t think anything significant happened from my side for her to not want to talk to me like before? But still, I noticed small things like she doesn’t laugh when I joke around and she swapped using a more affectionate nickname for a more neutral one. Idk maybe she started dating someone, we never talked about relationships and it feels weird to bring it up out of the blue. She reassured me she wants to talk and nothing changed as I’ve asked her about it since I noticed the changes in our interactions but still All in all, I can’t shake the feeling that if at one point she perhaps was interested in me more than being a friend as she got to know me more and saw me at times struggle to fully express myself due to stutter she realised it’s a deal breaker for me. Anyone else here experienced something similar or can offer some outside perspective? I’d be happy to hear your thoughts
