If there are no current barriers keeping the two of you apart, it may be that in a past life you were blocked from being together. It is interesting that you fear his anger over emotional questions yet you have apparently never experienced it.
I would suggest taking your relationship into a new area - perhaps a relatively neutral one, if you're scared of losing this entirely. Not knowing what is the usual area for you, my suggestions may not be that apt. Possibly come up with an event you'd like to attend some distance away and suggest that he could go with you because you don't want to travel so far away alone. Ask him to a family dinner or event. Or suggest he come with you to do some challenging or sports-related thing you've never done before, suggesting you need the 'moral support' or whatever. If you're at a standstill, doing new things in new places may help that standstill to end naturally... or it may show you there are some limits in place, rational or not.
The problem with these "stuck" relationships is that they are often giving us some essential emotional support - so we don't want to kick it so hard it breaks rather than loosens up - yet they aren't giving us everything we genuinely need, so we are always left in an emotionally weakened state when all is said and done.
I hope this helps. I really felt moved to mention the past life potential to you and registered just to do so.
