soo my step mom told me 2 weeks ago that she had baby stuff for me and the next time I come by I get my brothers I would get it from her. I just texted her to let her know I was going to be there tomorrow to pick up whatever she had around and she told me very rudly that it's not up to me when she gives me anything, she is busy so I must wait to get things from her. made me feel like shit because my dad told me okay and she is pushing everything back and being a bitch!!!!! ugggggggg I'm done with her for real
