Feeling completely alone. I know I have my kids and they are the best thing in the world but I feel like I just lost the closeness between my husband and I. Not just that but his sister always seems to take his side even when he was in the wrong, so the friendship between me and her is gone. I was so excited for her to have her baby but now I won't be asking how she's doing. I'm just done trying with everyone. 💔😔
