This is probably a classic question. A year ago in my BP days I confronted her about it and her hamster went into warpspeed to rationalize it.

What are the correct things to do in this situation other than:

Improve myself to re-win her respect (lifting, career, etc)

Not complain about lack of blowjobs (OI)

possibly leave (never date a girl who won't do sexual things for you she's done for an ex).
