I knew I should have hidden this thread 
OP, love. I'm not here to bully you. I'm here to help. I have said that we at MN will be here for you in whatever way you need us to be, whenever you have any doubts, quibbles or wobbles?
I would love it if you could come on here and post stuff for us to say, Nope, that's perfectly normal, you are fine and DP is being spot on about xy or z.
Sadly we don't think it sounds like he is. Oh he is telling you it's for your own protection, but then he would really wouldn't he? These people, especially the emotional abusers will tell you stuff to make you believe them. Emotional Abuse is in some ways harder to spot, harder to deal with and harder to heal from. If he were a good guy he would not threaten to leave unless you did what you were being told, he wouldn't tell you that you are hurting him by not behaving, none of this.
If you get a black eye, a few days, a week and your body will heal. You get told you have no opinion, are worthless, can't make your own decisions over and over and over again, but all in the name of protecting you. When you realise that his protection has eroded every fibre of your being, so you can barely leave the house, or defer to him on everything, for fear he will leave you, let me tell you it is worse than being caught in a trap, you can't even gnaw your own leg off to get out. Those hurts don't heal, ever. You have to go fix them yourself.
It comes as a shock, but he's not belting me, he's never raised a hand, but threatening to leave you is textbook, really it is. Telling you what you can and can't do so early on, with threats is textbook, they all do it.
Eventually he may raise his hand when you say no, when you say he's not going to leave and get bolshie with him, he might not, but then he'll probably have moulded you into someone who does as she's told by then, he might not have to get physical, you will be trained to comply, or else.
I don't mind if you leave today, tomorrow, next week, month or next year, I would hope it's as soon as possible. It took me 10years, I think you may be smarter than I was. But I know you have to do it in your own time.
When your time comes, please don't forget where you will always be welcome, where we not one of us will think you failed (cos you didn't) or that you are an idiot (because you most definitely are not) we will give you a great big hug and cry with you if that's what helps you. PM me if you ever need anyone to listen. Nothing you can say to me will scare me. ever.
PLEASE promise me one thing? that you buy Why Does He Do That by Lundy Bancroft? It will help you heal from the ex and it may help you form a new healthy relationship with others.
