Confession: I cheated on my boyfriend and I don’t feel guilty. I feel guilty for the fact that I DON’T feel guilty that I cheated on him in the first place.

Request for help: Is there something wrong with me?

For as much as I imagine people who read this are going to go ‘no you don’t’, I really do love my boyfriend. I want to spend the rest of my life with him, we have plans to move in together soon and I’ve just got a proper job which means we’ll be able to afford it…things are moving forwards for us, and I’m excited and I’m scared, but I know it’s what I want.
I don’t feel guilty because in that moment when I kissed someone else, I knew I needed to be physically…wanted? I wanted someone to want me, and I got that. [Context alert: my boyfriend and I have had to live really far apart for a couple of years, seeing each other once every few months.] I’m not emotionally attached to the person who I kissed, or anyone else but my boyfriend, and if I’m honest…I don’t even know who this other guy was. I was out clubbing, I spoke to him for like half hour, we made out, then we parted ways.
I know that s***** contact can be meaningless; and it was. That’s why I don’t feel bad.

But I also know that that’s kind of twisted.
What can I do about this situation?
