So sorry to hear!Mittens is being very comforting lately while I am in pain from a ex boyfriend inflicted injury. It's really hard when the pain hits but he has helped me through it. I don't know what I would do without him. My boyfriend banged my head against his truck door repeatedly and I have a lot of back and neck issues from it.
Hopefully, he will stay your "ex" forever. If not, don't be afraid to seek help. You don't have to put up with stuff like that. Document all doctor visits, in case things have to go any further, which I pray they won't.
