It most certainly will not get better. You can count on that with certainty. The sooner you can gather strength to leave, the better it will be for you. Contact you state coalition for domestic violence and/or a local shelter. Some areas have resources that will put you up in a hotel for your safety.
Chances that this will get worse are eminent. You CAN do this! Be safe.
Girl, leave! The abuse will escalate, he will apologize and promise not to do it again etc.
You need to live yourself and yhour life, you deserve better, I know it’s easier said than done … but you don’t need to be in an abusive relationship.
Seek help from Domestic Violence support groups, make a police report, obtain a protective order. Call the DV hotline they will guide you in the right direction for support groups and DV support system within your area. Good luck and stay safe.
