The math is correct, but I don't know if those priors are realistic. Particularly the "10%" one. I miss like 50% of calls in general, having nothing to do with who's calling me. And remember that the "probability that she's over me," should be probability that she got over you since the last time you checked.

Wouldn't that be redundant?
Solve for: The probability that she's over me given that she didn't answer my call.
Estimated probabilities:
The probability that she'd miss my call given that she was over me: 90%
The probability that she's over me: 30%
The probability that she'd miss my call given she was not over me. 10%
(P(over me|missed call)= P(missed call|over me)*P(over me)) / (P(missed call|over me)*P(over me)+P(Missed call|Not over me)*P(Not over me))
P(O|M)=(P(M|O)*P(O))/(P(M|O)*P(O)+P(M|N)*P(N))
P(O|M)=(.9*.3)/((.9*.3)+(.1*.7))
P(O|M)=(.27)/(.27)+(.07)) = .27/.34 = .794
Probability that she's over me given that she didn't answer the phone: 79.4%

EDIT: Something I've noticed here is that people are pointing to the chosen priors and saying that they seem unrealistic.
In our 3-year relationship, she almost never missed my calls, or if she did she would contact me back as soon as she realized that she missed my call. In the current situation, she did no such thing.
EDIT2: Yes, we broke up. Sorry I didn't make that clear.
