Hi silentangel, that's great that you're thinking about/looking out for yourself and that he's agreed to counseling
As you know, it isn't as easy as flicking a switch or just telling yourself to trust someone, it can be a journey especially when you've been hurt in the past.
And there's that line between not trusting someone when they are able to be trusted, and trusting someone not trustworthy because you think you "should"/"you're being unreasonable", you're not seeing/validating the "signs"........or just because you need to be able to trust someone and they're just "there".
But it does sound like he's given and maybe giving you some reasons to be hesitant so counseling is a great way to go, for you and for him.
