[myPESTICIDE]

so this girl and this guy get married and the guy makes it very clear that he doesn't want kids any time soon because they can't afford it, etc. so i don't know when or how long after yet but the girl gets pregnant and can't tell her boyfriend for months until he starts getting suspicious because she claims she's going to her friend's house but really she's going to doctors appointments, and he finds out when he gets suspicious and calls her friend and she isn't there, then he find a phone number in her purse and it says darrell or something on it but really it's the doctor's phone number, so the guy thinks she's cheating on him and when he accuses her of that she has no choice but to tell him. what should his reaction be? should he be angry or just upset? how should it end?
