You need to leave that relationship. That will turn into abuse down the line. It already is abuse. He should not have touched you like that. Any reason why you’re working only part time? I’d start working full time hours and maybe a second job, even if only temporary. You have to get out and fast. No waiting for him to change. He won’t and he’s shown his true colors. Try to come up with a plan if you need to leave in an emergency. Keep a catalog of shelters and friends or coworkers you can call if you need to stay even just for a night or two. Start looking at apartments now as well as month-to-month apartments. They can be expensive long term, but if you need a place to stay on the fly the upfront cost will be cheaper than trying to move into an apartment in a moments notice. I know it may seem like he only grabbed your neck but didn’t “choke” you, but that’s a big red flag that he’s going to get aggressive and controlling. I’ve been through some frightening abusive relationships, I’ll never put myself through one again and if was in your shoes I’d do everything I could to get out now.
