^^ITA.

Nothing a woman (or man) ever does, warrants (or causes) any kind of abuse. Period. If someone is going to kill their SO, they have been abusing them already in the past and killing (especially a murder-suicide) is the final act. Abuse can escalate during and right after pregnancy, that's not the fault of the person being abused, it's the fault of the abuser. Coming home late after a concert can escalate abuse, that's not the fault of the person being abused, it's the fault of the abuser. Anything that a victim does that indicates to the abuser that he/she is losing their (perceived) control, will escalate abuse. It is a fact--that's not the fault of the person being abused, it's the fault of the abuser.
