RR, Seems like he still cares for you or else he wouldn't be doing all those little things for you. Be sure to show a little appreciation in return but dial it down a bit. Men need to feel like they are good providers or else they get their feelings hurt. A simple "thank you" goes a long way.
And honey, stop bringing up the OW! Just stop it! Each time you do you're only hurting him because it reminds him of the guilt and shame he has over having to juggle both of you. You'll better your chances by avoiding those OW talks at all costs.
BTW You can bet the OW is jealous of his good time with you and taking care of you that he could be with her. So long as you aren't needy for him and driving him away the OW will be soon enough. Then she NOT YOU will be the woman saying "I need more and more, gimme, gimme!" at him for a little attention. And how will that make her look? There's one thing you've got she doesn't...DR and DR.com. You let her be the spoiled brat, you know how it's going to end and just what to do.
