Most of the chapters in my section have brothers dating brothers, and many of them getting married after graduation. (I've got one wedding in June and had 2 last year.) My chapter in particular had some basic policies on dating brothers:
1) Brothers were encouraged
NOT to date pledges.
2) Brothers were encouraged
NOT to date their littles.
3) You are to keep your personal relationship out of chapter meetings and decisions.
Over the years we've never really had any serious problems from brothers dating. I dated a brother as a pledge and later as an active.
We broke up and still had to be on exec together, but we remembered that our personal problems do NOT belong in the chapter.
Policies reminding the brotherhood that they shouldn't let their personal relationship affect the chapter usually help to remind people about that.
There will always be those who see APhiO as a dating service, that can't be helped. It's the same as those who see going to the gym or to church as a dating service.
We are brothers because we have something in common. Some of the happiest marriages I know are between brothers, especially ones from the same chapter, because they know each other so well. They know their faults and their strengths, and they respect each other. So I say, to those who are dating brothers, CONGRADULATIONS; to those are out there looking for that special someone, you know that the brothers in the fraternity already have things in common with you and that you trust them. Why not start there?
