My boyfriend keeps "joking" that he wants to impregnate me?

Thank you for this, it was very insightful. You're perhaps right about him not knowing how to express his feelings regarding the matter.

I think what I need to do about this whole situation is just have an in-depth conversation about it and see where he's at. Because we are pretty open with each other. I guess I've just been slightly worried about this.

Thank you!
