Hubby is confusing me!

For 2 years he had not wanted a baby. We already have 2. On Friday we had a few drinks with friends and ended up having sex. It lasted WAY longer than it usually does. Then he starts telling me he is going to put a baby in me, right then.. So after him cumming 3x(wow), I told him I wanted to talk about it. Then he said he just felt like it. Sooooo the next day while sober I brought it up again and he told me that it was just a one time thing and that he felt like he needed to. Am I wrong for feeling lead on?!? I want another baby but I don't want him regretting it either. =( advice??
