Extreme life and partner change. 14 years and no baby to 5 months with someone who wants one!

I got out of a relationship of 14 years recently. I’m 31 (F) ex is 31 (m)

I begged for a baby for years and for marriage and it took him 13 years to propose and he still put off having babies or even taking the risk to have one. I lost my marbles after having a miscarriage and started drinking. I lost my job, totaled my car, and ended my relationship. Fast forward to a man who is 37, ex co worker. He buys me flowers and treats me like an actual angel. We moved in together this past month and he is almost too good to be true. He cooks, cleans, doesn’t make me feel bad, doesn’t care if I work, and wants to have a baby with me whenever I decide. I’m so confused and conflicted. But I’m also…extremely happy? This man lights up my heart but I don’t wanna hurt my ex by moving on too fast… however I’ve waited my whole life for something like this. I’m not sure how to approach or tackle life right now.
