From what you have said, and from what others have posted, it really did seem that your guy had already made a deicsion. He clearly hadnt just changed faith mid relationship with you - so he must have had some idea of what he wanted to do with his 'marital life' before having a relationship with you anyway - so its always been at the back of his mind.
When your in a bad or emotional situation with your boyfriend or even family members, you will always act in haste and repent at lesiure. in your case, you've finished with him there and then (acted in haste) and you regret what you did (repent at lesiure.)
Usually there is a 'cooling off' period - for example, when one of my Exs dumped me, he tried calling me an hour later, but i refused to answer my phone as i was confused and upset. A few days later when i composed myself i rang him back. Wait a few days before assuming that he doesnt care because he hasnt messaged you back yet.
