In response to what you said, yeah, I understand that, and even though we've been going at it on and off for six years now directly because she was too possessive, shes made more of an effort since before the engagement and thats why I decided it was worth it.
In short, I dont think being members of the same message board will total the relationship. I personally know at least two couples who actually met on message boards I belong to, one of whom are married and one of whom are very close now.
Its all a matter of what happens in 'real life'
As long as we spend a healthy amount of time together and apart outside of here, this wont make or break our lives.
