As JWs, we were expected to be 'perfect'.
You said that your BF did not believe the things you told him about your life, from the very beginning of your relationship. That is a red flag - he has trust issues, so can *he* be trusted?
This need to please, can be especially difficult to overcome when we have newly left the LIE. We were taught that leaving the b'Org meant we would always be alone, so the fear is ingrained. On top of that, the JW love is conditional, so our neural pathways are set on one message: Tell people what they want to hear, or they won't love you! Your BF reinforced that message by being mistrustful of you from day one.
That's not to say he is necessarily a toxic person - most people have some issues - that is for you to determine.
You don't need to hide who you are, in order to be loved.
New neural paths can be created. Just like in nature, we can forge a new path, and over time, it will become the natural way to go, as the old path gets clogged with undergrowth and becomes harder to find.
This is one of the purposes of Cognitive Behavioural Therapy. Once you figure out what you need to do (Transactional Analysis and other therapeutic techniques are very effective), then change your behaviours.
Here's a good example of one thing I had to change. I had that 'bad parent' in my head who always said "That was stupid!" So, every time I had that abusive thought, I would correct myself and say......... "If I had to do that over again, I would do it differently.." Healthy people make mistakes, too. : ) After a while (and it took a while), I stopped thinking "That was stupid", and would think "Doh! I'll do it different the next time". I created a new neural path, and this meant I was no longer punishing myself unfairly.
Do some research online, read some books, and a great choice may be to see a counsellor or therapist to help you work through these issues.
But at all times, remember this:
You is kind. You is smart. You is important. ~ Kathryn Stockett, The Help

EDIT: Just saw your post, Van - agreed. As Dan Savage would say, DTMFA : ) Every relationship is a learning experience, though.
