I'm so confused
This happens a lot, especially on weekends.
Partner looks sullen , gives off bad energy and appears to be sulking. Barely speaks. I try and ignore and act as breezy and caring as I can. Eventually I have to ask what is the matter are you OK. Partner denies anything is wrong and carries on looking sullen and being short with me. I say OK and carry on with my day. Eventually partners mood ends up affecting me and I'll get noticeably down or I'll get irritated by it. In response my partner will say nothing was wrong but it is now etc and make everything feel like my fault. Then after this Partner will cheer up.
What is this weirdness and has anyone else experienced this
