UPDATE: Feeling rejected and confused

***UPDATE: when I came home from work yesterday, my husband had a case of my favorite flowers waiting for me: tulips. When I asked what these were for since there was no special occasion coming up, he gave me a long hug and apologized for the previous night. I was completely shocked. Based on his behavior the night before, I thought he would just never address it again. He said he wanted to start trying to get pregnant in March or April this year as he’s trying to get his parental leave benefits at his work finalized. Thank you for the advice and support!***

So my husband and I recently decided to try to get pregnant in 2020. We’ve only been using condoms for protection but last night when we had sex he asked me “should I put one on?”. I said “it’s up to you”. He appeared confused and I clarified, “well we talked about having a baby so you don’t need to put one on”. He got upset saying he wasn’t ready for this conversation. I was left feeling confused because we had already had the conversation 2 weeks ago. After sex he made himself vacant around the house and later acted like he didn’t know why I was sad and didn’t see a need to apologize or to make amends. What should I say/do now?

A little background info: I’m 33yo and he’s 37yo. We’ve been married 18 months and this would be our first kid. He’s traditionally struggled to make major life decisions and has always been a slow, reluctant decision maker (took him 5 years to finally propose to me; took him 3 years of shopping for a truck to finally buy one; and don’t get me started on his procrastination with buying a house. We’ve thought about buying a house for 3 years.....we are still renting).
