Insecurities

I recently got back with my husband after a yr seperation. I moved in with the inlaw and theirs a friend of the family that has been staying here she seperated from her husband about a year ago. So since ive moved back in ive noticed how her & my husband get along and honestly i dont like it. She is suppose to be my friend more than his and at times they takk more than me & her. I feel like he checks her out and tries to conversate more with her than me at times. It is the most ugliest feeling to feel like your husband might be attracted to a person that is currentlh living in the same home. I feel like talking to him at times and getting this off my shoulders but i dont want to over react and i dont want to create a big situation out of this. I feel like if i talk to him about it he'll tell the whole family and cause drama & of course i already know he will say "you're crazy". Any advice.. am i exaggerating?
