I am just like you; We had trouble with BFing so I switched to EP. The only reason that I am still pumping is because A) I produce more than enough to feed her and B) I'm not going back to work. If I went back to work, I too would probably be done with pumping. Its hard because we can't just whip out a boob or just get a bottle of formula ready, we have to pump and feed a baby which is majorly time consuming.
Whatever you do, just do what makes you happy. If your not EPing and a happier person because of it, then so be it. Your LO will be getting fed and that is the main thing. Like I said, if I was going to work, I would probably be done. Do what you want to, and own it.
