Lonely

I'm 6.5 months postpartum. I have nobody except my Husband which typically don't mind but he's planning on switching jobs soon which will take him on the road. I can't go with him because we have 3 dogs that we can't just rehome (not easily) plus they love their baby human. I have no friends, they all just up and abandoned me when I got pregnant. My husband's friends have taken me in the group so effortlessly along with all of their parents which I'm greatful for but I also still feel like their my husband friends not mine even though they adore our son but when he leaves I feel like they will to. My family lives hours away and never come see him, his family lives 30 mins away and the only way they have seen him was when we go over there. My dad calls maybe once a month. His family maybe every 2 months. I've asked for help from his mom and she says she will but when it comes time she comes up with some excuse then proceeds to say she feels like we don't want her around when I've told her over and over that we do but when she doesn't put in effort how does she expect us to. I feel alone and lonely without my own people and friends. Me and my boy go get coffee and walks together but it's just us. I feel like me and my son are burdens to everyone so I just stay to myself and raise my boy. Him and his dad are my whole life and I'm so extremely thankful for them both because they both saved me and gave me a reason to live, but it's lonely.
