Breastfeeding or Formula?

I am a FTM and was all about trying to breastfeed because it's healthy for the baby. My DH and I went to a class tonight about Breast feeding. After the class it just turned me away from wanting to do it. I really just have no interest anymore. My DH is supporting either way but would prefer formula, so he can help me with feeding. I'm feeling guilty that I have no interest to Breast feed now. Anyone else feel this way?
