I seriously feel like me and my SO are slowly coming to an end. I been in bed sick this will make day 4 and not 1 day has he sat with me and rubbed my back while I throw up, or go out his way to feed me. or call from work on his break to check on how I'm doing. instead he wants to get drunk and get mad at me cause I don't feel good enough to have sex with him and apparently since we been together so long sex makes up half our relationship and it's become a need or so he says!! whenever I don't feel good it's always his mama taking care of me and when he don't feel it's me taking care of him. how fucking backwards is that shit
