Disappointed

So apparently my husband told his dad what we plan to name our baby boy if and when we get pregnant. This happened on Christmas day then later in front of everyone his dad asked me what we would name a girl... well here's the thing I told my husband I wanted to keep the names a surprise but I guess he didn't remember me saying that... he feels really bad but what can we do now? Anyway I went ahead and told them the girl name because his mom was hardcore listening in and I didn't want to make it a big deal and seem like a B. After I told them his mom and dad looked disappointed and the topic was abruptly changed... they didn't say oh that's pretty or anything. Idk if it was because they didn't like the name or if it's because I didn't use her name. We are using his dads name as our future sons middle name but we are using my mothers middle name for our daughters middle name. Uhg. Do y'all think the names are bad? Elias Roland & Arabella Rose
