Edited to add a self-admitted validation bit:
My new job is literally 3 minutes away from my dad's house. I have an hour lunch break and not really anywhere to go during that time other than the stores nearby my work. My stepmom and I got lunch today (I initiated this...she hardly ever reaches out to me) and she told me she'd only be comfortable with me coming over once a week, and only on one certain day (e.g. only coming on Mondays). It kind of hurt my feelings and makes me feel unwelcome because my dad has always said that this is my house too. I wish she would have just said I'm welcome anytime - it's not like I'd be coming over all that much by my own volition anyway. Am I overreacting or is she being shitty?
