My gf was telling me about this behavior she noticed on Facebook.

She’s noticed some women will suddenly announce they’re getting married to some guy with zero indication they were dating prior to the announcement.

In some cases, the dating was going on for more than a year. After announcing the engagement, the floodgates open up and they’re posting selfies together, referring the guy in their updates but before that happened, it was like the guy never existed. Zero disclosure about him.

My read is these women either:

A) Want to save face in case things don’t work out.

B) Wanted the best of both worlds. Be in a relationship but present to the world they are single so they could branch swing / trade up and not been seen as a shameless sluts in their social circles.

Am I right or am I missing a third reason?
