So my "best friend" and I aren't exactly talking..now I'm the one that chose that. She did come up to the hospital when I had my son. But it was a day where I was miserable! Not towards her. I was just out of it. She came to my house after the hospital cause we got sent home. But I ended up passing out for 7 hours so I didn't really see her at my house. After that she didn't really text me to see how everything was or anything. Just sent me pictures of her and her man in bed and him cooking. So I would send back pics of my son and she completely ignored it and just kept on going with this guy. So I got upset and so did my BF. She never asked "how's Travis" "how are you feeling" "when can I come see him". Nothing. Then she invited us to a party. But they way she invited, idk, got to me. I didn't answer back cause I got distracted with my son and stuff. And she's friends with all my old ones and my ex and my BF wants nothing to do with any of them(understandable) and I don't really care to see them. But I am bad at saying no to people. I don't know what to do. Like it just bothered me that I get the impression that now that my son is actually here, she doesn't care to come over. And she just figured she'd invite us to the party..(her words)
