I think this has come through having to endure hell and back...
Yes, AE, going though painful times does affect you and can make you question yourself, your previous behavior, and your core beliefs. Trying times have affected me and changed me, and I dare say they have done that to many others on this site.
The question you must ask yourself is this: Am I being true to what I really believe, or am I staying in a comfort zone? It's a wonderful situation when it's both, but being false to yourself just to ease the pain doesn't work in the long run. I'm not telling you to change; only you really know if you should do that. If you really believe the Watchtower's teachings then by all means follow them. I didn't ask my Ex to change her beliefs that I don't share, and I won't ask you to do that either. But I do suggest that you should look at yourself honestly, look at your beliefs honestly, and look at your relationship to God honestly. Base your decision on what you see there, so you can live at peace with yourself. That is the way to make decisions you will not regret further down the road.
I wish you a good journey on the path of self-discovery!
