Does this mean I’m not in love anymore??

So I’ve been with this man for 5 years and married for almost 2 and before I was so insecure because I got cheated on several times by different guys and today I had NO PROBLEMS with my husband looking at a skinny girl in a bikini. Like I had no heart feelings no jealousy NOTHING. Does this mean I’m not in love with him anymore or is this what being secure feels like??
