Am I just pregnant and hormonal? Lol

So my husband and I were driving by a house and he said "we used to know the people that lived there." I asked him who is "we" and he said him and his ex. Maybe it was because we had just bumped into his exs friend not 5 mins earlier but that made me upset that he referred to him and his ex as we. Sounds so dumb and it probably is since I'm hormonal but am I totally insane? Lol
