Feelings of depression

courtney🌻 • 21. Lucas Michael & Liam Scott - 9.25.15
I'm starting to feel extremely down. My boyfriend only seems to care about sex and physical touch. We usually "spoon" but I'm not 16 weeks with twins and I feel like my back is breaking and it hurts to cuddle and he just tells me I'm not emotionally with him anymore and it hurts. 
What's even worse is today is technically my birthday and I feel like he's just treated me terribly. I don't know what to do. I try to be emotionally there. We're having twin boys and I'm always telling him to rub my belly and talk to the babies and that's how we are "emotionally together" but he sees it as a chore. 
I feel stuck in this relationship because my kids need a dad. I need reassurance. I need a partner.
