lol No worries Soul. Type as much as you need.
I think Open Eyes NAILED it in a fantastic post...your ex, by virtue of you being so young when you were together and for the length of time, created an abusive relationship like that as your mental "norm," on top of everything else prior. To have such a radical departure from that in a guy who truly cares and loves you is naturally going to be a strange transition.
But you have to trust him.

Speaking purely in statistical terms, the sample of abusive people you've been exposed to is not representative of the population.

Your boyfriend deserves the chance to prove he's going to be good for you, and you owe yourself the comfort and peace of mind that comes with believing that. "Innocent until proven guilty," basically.
Best of luck to you both. God bless, and Merry Christmas.
Hugs,
