Struggling with Setting Boundaries in a New Relationship

this is just kind of a mini rant i guess. content warning: talk of consent (and lack thereof) so ive been talking to this guy for about a month, maybe a little less. and right off the bat he told me he was a "safe person to say no to" and that he would never get upset or push if I ever said no. and like... I've just seen some contradictions. Like any time he's wanted to meet up I just havent been feeling up to it emotionally. Like I just didnt have the spoons. (and he springs these potential plans on me with like...a day's notice so I have no time to mentally prepare either) and ive had the conversation with him about like the spoon theory and how I'm just not gonna feel up to plans sometimes and he said he understood...but then he still pushes back every single time I try to say no to plans. and its frustrating but also...kinda rings some alarms bells. because his main justification is trying to push me out of my "comfort zone" like...as if he knows whats best for me. and I appreciate that he's trying to help, but he's just making things worse. and I very much do NOT feel safe saying no to him anymore.
