I’m a guy fwiw and think this is the best comment I’ve seen so far on the thread. Mostly because: I agree with it, think the advice/reasoning about ulterior motives and the luxury of time is wise, and lays out some good alternatives for OP.
I think that if a motivation to create a child with someone is expressed plainly and clearly, it is far from an ulterior motive. It's a genuine motive.
Best of luck to the above poster and OP
