DH is my second hubby. My first husband had an affair and let me and the kids and I am a little paranoid about the same thing happening again, especially as my new DS also had an affair (not with me) which led to the breakdown of his marriage. So, someone I have been friends with for around 12 years who is actually the ex-wife of my ex husband's best friend, has come to stay for ten days. She is from Argentina but usually comes to the UK once a year and asks to stay with us. This time she asked to stay for 6 days but said yesterday that she needs to stay for an extra 6 days. She is a good house guest overall but I am getting really paranoid about her interactions with DH. DH is Spanish so they frequently break off discussions to talk in Spanish in front of me and share little asides here and there. She is also hugely tactile and very animated and often touches DH's arm etc when she is talking. I am pretty sure there is nothing in it but I feel on edge and paranoid with her staying, especially as I may be away one night this week with work, leaving her and DH in the house alone together! She recently got married so I don't think anything would happen but I keep torturing myself. I am also getting a bit tetchy as she seems to expect me to make her breakfast/hang out when I am trying to get DSs dressed and ready for school and myself off to work. Am I being tetchy/paranoid or is there something in this?
