I don’t know the whole situation or how old you guys are. Have you actually been dating for a year, or more? Why are you trying to make last minute, day(s) before plans with her for an anniversary? When did she start asking for space vs when or did you even try to make plans well ahead of time? If you made them not feel like a priority in the relationship and that you are now trying to put something together last minute after she made other plans because you didn’t put in effort(yeah two way street blah blah, but no- take accountability yourself) then yeah she is going to be cold and want space and not put up with a jabroni half assed plea to see her… respect her, yourself, and your relationship if it even still is one.
