I got engaged to my long-term boyfriend.

For years I have been dealing with infertility. 5 years ago I was diagnosed with PCOS, and it took me THREE YEARS to get my period back. Now I'm pregnant and have pcos, and my husband to be is freaking out about it. He says he's gonna be a father but doesn't want to marry someone if there's a chance that he won't be a father. I know he's been distancing himself from me because of the fear of us having a kid with my pcos. And now he's telling everyone that we're engaged, but I'm not engaged to someone who's gonna leave me for not being a mother-to-be. He's been lying to me, and I feel like I don't want to be in a relationship with him anymore.
