Aww tough one... I wouldn't ever marry again.. or I don't think I would.. when i was with my last bf we talked about that.. he said he would never marry again and I said I wouldnt.. but I did always think that even though I wouldnt want to marry again, I WOULD love it if he asked me... just because, I guess, I would feel that he truly loved me enough to do something he said he never would.. So it would mean a lot that he asked even if we didn't actually marry..
I do believe in love... I always will, I love love, I love people who are in love, nothing makes me melt more than a man saying how much he loves his partner/wife.. and I understand that marriage was partly about making that extra commitment.. but I think I truly don't think that in this day and age it is necessary.. You don't need a ceremony to commit, you don't need to spend thousands...
And as for kids.. well I think as long as their parents are happy and love each other then it really doesn't matter to them if they are married or not.
