What are your relationship dealbreakers, besides religious requirements? This is intended to be a fun but slightly serious thread.
Seeing how a lot of relationships wind up being broken, and seeing how there is often a lot of pain involved, I hope that you do not mind if I give a totally serious answer here.
For me, the primary deal breaker is if a woman will not truly let me know who she is on the inside. I mean, that is the real person, and if I am not granted access to the real person, then everything else, in my estimation, is just superficial, and eventually destined for disaster.
It just so happens that I am a very deep and passionate (I am not talking primarily about physically...especially since I truly feel no physical attraction to a woman who shuts me off internally) man, and that always seems to be a problem. In other words, I seem to always encounter women who are focused solely on the external, as opposed to matters of the heart, and I am pretty much the polar opposite.
I am sorry, to an extent, for momentarily interrupting the fun here, but I regularly encounter people who have basically been crushed by bad relationships, so this is a very serious matter for me. Also, by no means were any of my comments meant to sound detrimental to women as a whole. This is just one man's experiences, and my experiences do not apply solely to relationships that might one day lead to marriage by any means. Instead, my experiences definitely deal with friendships as well. If I cannot truly know a person, then I simply cannot be their friend because I care about my friends, and who they truly are on the inside.
