I have honestly felt the exact same way you do right now. When I returned from Afghanistan, my mother lodge all but ignored me, while I was gone personal politics, and ego nearly ran it into the ground. Upon my return a hostile take over of the line-up happened and I was given the cold shoulder, and given absolutely no reason. I wanted to tear up all of my due cards and leave, because to me that isn't what Freemasonry is about. I started to attend lodge somewhere else, and I finally feel like I found my Masonic forever home. While I am still a member of my mother lodge, and love some of the brethren dearly, it isn't worth the aggravation of attending. I haven't demit, because of my ties to some of the brothers, and I know it would hurt them, but I made the choice not to pollute my Masonic experience any more.
I am now more active in Masonry than I was after I was first raised. I have found brothers, companions, sir knights that challenge me, and make me a better man every day, I am writing more and am feeling the personal experiences that I read so much about. For that I am thankful I just didn't give up, and went on my not-so marry way.
Please think of this as you weigh your future masonic options.
