A few examples of DV from Women's Aid site:
Threats: making angry gestures, using physical size to intimidate, shouting you down, destroying your possessions, breaking things, punching walls, wielding a knife or a gun, threatening to kill or harm you and the children.
Physical violence: punching, slapping, hitting, biting, pinching, kicking, pulling hair out, pushing, shoving, burning, strangling.
Denial: saying the abuse doesn't happen, saying you caused the abusive behaviour, being publicly gentle and patient, crying and begging for forgiveness, saying it will never happen again.
0808 2000 247 - ring it, ASAP. 999 - ring it, ASAP.
You know that to leave will be hard - it will, there's no doubt but it will be better, surely, than living in fear in your own home?
I have been through this - my ex locked me in the house and did all sorts of other mental cruelty - he also slapped and punched me.
Please, please think about ALL your options - you do NOT have to put up with this and you are NOT to blame - ever.
