Is the non commitment trait to blame for this

My sim married a townie(yes, it was Don) who has the non-committal trait. He went thru with the marriage. Then he started becoming "tense" all the time and it would show a bubble of a wedding ring over his head.

I wonder what mood he was in when she got rejected? If Don is in a happy mood, mine got rejected because their friendship bar was half way up, but the romance was more (this happened before the marriage though)
