Poof! Pregnant with fiance's kid, he wants to be with his ex/BM
That was up for two minutes.
Please young ladies...if a man doesn't want to marry you and you're pregnant with his child, then don't worry about "how do I deal with our marriage"? DON'T MARRY HIM.
And for the love of all things holy, don't ask, respond, and delete immediately. It's just....annoying. Gave you the advice I'd give my step girls. And I meant it. Cut your losses. He's just not that into you. Read it again here anonymously if you wish. I really hope you have parents who are guiding you similarly.
