dating a woman who is pregnant. Someone who may be single or is in process of ending a relationship.
OR is in the process of ending a relationship? OMG. NO. Why would I date a gal who's pregnant with her BF's bay-bay, who she's still with but is going to (knock on wood) break up sometime soon? Sheesh.
Unless it's someone you've already known and set for an unusual but positive situation-- no, one shouldn't put themselves in position of nabbing a new BF while pregnant... certainly shouldn't be out on the hunt For a new one.
