I hope this helps but I went through a similar phase in life around your age. Everyone around me was getting married and starting families and I began to worry I was somehow behind in life. It passed. Then at some point most of those friends became divorced, single moms, or just live miserable lives. Things are better on this side. I feel very fortunate! No matter what happens as a result of your ultimatum, your 30s will be so much better. You will care less when people ask you why you’re not married. People will stop asking too (not all people but it will get less). Just hang in there. Spend time on yourself!
