I'm working on setting some healthy boundaries, and a I've noticed a pattern where if I ask my partner what he's planning he deflects. I'm not talking huge, I'm talking about a weekend recently when we were supposed to see his mum and I wanted to know the timings but he never provided them and this weekend when he's thinking about going away for an afternoon and a night and I wanted to know if that's happening or not. It tends to start with vague things like he'll sort it out later, then progresses to maybes or talking so quietly I can't hear, or even silence when I raise the topic, and if I really push for an answer he derails the conversation by bringing up things he's upset with me for. I know this isn't normal. I know a bunch of you are going to tell me to leave him, which I might. I think either way I need a game plan for these vague occasions. At the moment I'm going with - "Okay, I need some certainty so I can fix my plans, so I'm going to presume you're doing x. On that presumption I'll be doing y." So for example this Sunday when I don't know if he's going to be in or not I've said: "I'm going to assume you'll be out from midday, and I'm going to spend some of the afternoon with my brother and his family so I get a bit of support with childcare while you're out."
