Well, I asked my husband. He is social, so I hope this helps! He said that you should go with your gut feeling. If your husband has been social since the day you met him and you have never felt like he may have been cheating, then he may be interested in another woman. Whether he is cheating or not, his interest in another woman could become an issue. He suggests that you write down why you feel like he may be cheating and then ask him about those changes and reasons.
