So I've felt some type of way with how my cousin acts with my husband. They work together and we used to hang out often with her and her now ex. She's a flirt and my husband has said it himself that she's a flirt. Any way for the past couple years she has done small but yet annoying things that has made me think she's into my husband. This weekend was my baby shower and she was sitting next to me and I could see her texting away back and forth. Last night I found out she was texting my husband for our home address to mail the gift she got for our baby. Again I was sitting next to her and not to mention we have a registry that has all the our info needed to send gifts. She could have asked me for the address.. I was very upset last night and anoyed. My husband has reassured me there's nothing going on and he woul never flirt back with her. I don't know if I should say something or just let it go and just say something I'd it escalates.. what would you do?
