I really just don't know if I even want the relationship to work out. I honestly wonder to myself if I am just selfish since it isn't going as quickly as I had wanted before. I truly am just confused right now.
It's only been 1-1/2 months since D, I think maybe you got a little impatient. With D your W probably felt like the pressure had been removed and thus she was more comfortable spending time with you again. But the kiss was too much pressure too soon. Honestly I don't blame you, things were going well and "fortune favors the bold", I can't say I would have done any differently than you did. I don't think you need to worry too much about it, just go back to giving her time and space. Go back to acting "as if". Don't bring up the kiss, just act like everything is fine no matter what.
