My husband is negative!!

We’ve been trying to conceive for 9 months! Finally we got our BFP!! My husband was so excited he cried! Well now all he talks about is the money and we’ll never be able to buy a house or go out or afford bills! He’s been nothing but negative!!! I don’t think he seems to understand how his negativity is affecting me because I said him to stop being negative because it was upsetting me and he just said “K” and stopped replying! I had my daughter at age 21 and did it alone and always made it work! I’ve lived with him since she as 8 months old and anything that had to do with her I paid for! Daycare was my expense diapers my expense anything for her was my expense so I can’t seem to figure out how he thinks it won’t work!! I’m honestly so sad right now and so hurt! He’s been so distant and so negative and I don’t know what to do! I was so happy to finally get our positive but hes done nothing but be negative I’m not excited anymore! I’m scared and sad bag he’s going to ruin all of this! We’ve always had a good relationship but I can’t take his negativity!!!! We both work good jobs make good money and have lots of money saved and a savings plan we plan on using!! Help ladies! Please just send positive vibes and advice!!!!!!
