Hi,
I went through the same thing with both of my kids. I didn't want to do the cry it out thing either, but in the end that was what worked. The first night was absolutely HORRIBLE. I'm not sure who cried more, me or my son and it went on forever. The second night bad but not nearly like the first. The third was SIGNIFICANTLY better (only cried for maybe 5-10 minutes). By night number 4 it was no longer an issue. With my daughter it only took one night - again it was NOT fun and it took everything I had to not go in by her. But, with Zoey it only took the one night. On night two she didn't call for me or anything. I woke up, but she didn't.
At 14 months he is simply in the habit of having mom come and get him back to sleep. He doesn't actually need to eat, but it's the comfort of mommy he wants. It doesn't help that seperation anxiety is starting at this age too. Does he have a special toy or blanket he likes? Maybe instead of patting his back you give him his "lovey" instead, which you may already be doing.
Good luck - it's never easy is it?
(FYI - You and I have a bit in common too. I've been married for 14 years - our son is 3-1/2 and daughter will be 2 in November)
