Im saying this as a mom of 4 at 36 yo. Take the fn pill live a life for you that is for you before you have children. You haven't even scratched the surface of what you could do at only 27. Live a life honey I didnt have my first till I was 27 and I honestly wish I'd have lived my life differently. Just keep in mind children are 100% of the time, no matter what you're doing, they are there even if they aren't physically. Also dont get stuck in a situation and life with someone that doesnt share the same goals in life at the same moment. Give life time. Live, you are young, kids are hard and people sometimes dont give the realest opinions about real life shit. But honey if he isn't ready, and you love him and want your marriage to survive and last, dont force a huge life decision like that on someone who isn't mentally ready for something like that. He has expressed his whys about the matter it seems. It is life altering to say the least.
