DP by nature is a quiet person however recently her quietness has changed from just being her to being quite blunt and snappy when she does talk, which makes me feel like shit. When I ask if something's wrong, she says 'nothing' in the most pissed off voice ever, and then continues to keep speaking to me like this.
Is this a normal way to treat someone? It's starting to really grate on my confidence - my logic is that if she's not in a bad mood, then she must really dislike me to speak to me like that. It's happening more often than not now, and she doesn't respond well to me trying to talk to her about it, either she tells me I'm being ridiculous or says that she's just a quiet person. As mentioned - she is quiet, but there's a difference between being quiet and not being very nice!
Also, we're both women. We've been together for just over two years. This behaviour began about a month ago. Any thoughts welcome.
