<human>: My husband and I share a workplace and a car. We work opposite shifts and one of us works while the other one watches our daughter. This one girl was hired two months ago and became quick friends with my husband. They work nights together and they are getting close. 

I'm a bad person and looked through his phone and Facebook (I know, we have just had issues in the past and I am not about to get screwed over again.)

So he has a really big crush on this girl, and now all of our co-workers know it too. On our one night off to hang out, his friends came over and they drove off. They went to the store to go flirt with her. 

In his defense, he is talking on Facebook (in private messages to his friends which he doesn't know I have seen) about how conflicted he is and they haven't done anything yet. He is really torn up about it.

Now I have to go into work where I either have to (a) over-react and be that bitchy jealous wife or (b) have everyone think I am a moron who can't hang onto her husband.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My husband has a crush on a co-worker of ours and is possibly emotionally cheating (is that a thing?). And I snooped on his Facebook and that is how I know. Am I overreacting?
