I was engaged right before I met my DH. We were 2 months from our wedding. He was in the Navy and stationed in Pearl Harbor. He had been the one to make weeding arrangements there, or so I thought. Three months after the date was 'set,' he told me that he hadn't done anything, and had never said anything to anyone about setting up our wedding. Worst part, I was suspecting him of cheating. That was it, I ended it and met my DH the following night. We became friends and then the rest is history. It was a hard couple of months, but I made it through. My friends helped me through and were a God send.
You are in my prayers and all I can say is wait a couple of years, because, like my ex, karma will hit him. (He got a chick pregnant during a 2-week stay, married her shortly after, calling me the day of to talk him out of it, had 2 kids and she walked out on all three of them after getting hooked on drugs. Its been humerous catching up with him every so often.)
