My best friend 🤦‍♀️

Okay so I have no idea what to do. I’m a mom and my best friend is as well. Our babies are close to the same age. I haven’t seen her in a while honestly. We both have our busy lives but we still text and keep up. Well I went over to her house yesterday for a play date. Well I went and got food since the babies where sleeping and I came back with the food and we start to eat and I hear my little girl hungry cry so okay I put my food down and go make her a bottle and I give her a bottle she’s Okay and goes back to her nap. Well not even 5 mins later her little girl is crying but she continues to eat and I told her I think I her kinzy crying? And she dead ass turns to me and said. “There is no way I’m letting my food get cold, she can wait.” I quickly lost my appetite and her little girl starts to scream Louder and I kinda sit there hoping she would go and get her baby a bottle because it’s a hungry cry it sounds like. But nope she still eating and taking her time at that point and I go in the kitchen and make her little girl a bottle because she’s SCREAMING like I’m talking about SCREAMING. And I come back and ask her I could lend a hand and go give her a bottle. NO. Is what she told me. Like you’re little girl needs you and I go in the room anyways to check on them and her little girl is reaching for me and crying little tears coming down her face and I pick her up and she just clenched on to me like no other and my friend comes in and she’s MAD. I felt so bad. I wasn’t trying to be a mom to her little girl. She was just crying so bad and so hard my heart couldn’t bare to leave the room with her like that. So my daughter and I get home and I get a real mean nasty text from her. Was I wrong? Should I apologize.. i really don’t want too because she makes me sick to my stomach just thinking how selfish she could be.
