I'm not married or totally spoken for, but have been through two marriages and a long-term relationship after the last marriage.
I think it is almost easy to see who's involved in a good relationship and who's not. The posts are often reflective, the subtleties in the attitudes of the posters are easier to read after a little while around TFP.
That said, I've renewed hope in finding a fulfilling, communicative relationship after seeing some of you here that are in (what sure appear to be) solid relationships. I'm really proud of you nameless kids.
