I am happily married with a D age 4. Few weeks back I asked my sister to babysit and she normally asks me if her friend who is a longterm school friend and who I have known for quite sometime, can stay too. Normally I say no problem, however I was checking my hubbys e-mail at work and this girl had sent him a friends request via Facebook. I didn't get one and havent had one still. When she came round to babysit with my sister, I made a joke about it and told my other half who thought it was funny. She denies any wrongdoing and said she couldn,t find me on facebook, but I am on my sisters page as is she. She couldn't have really looked very hard. I feel threatend a bit. That same night we came back early from out night out (10th wedding aniversary for us) and had a few drinks with them my hubby although he was drunk flirted with her. Bit confused. He is always home on time and is loving and attentive doesnt go out on his own and is model husband most of the time. Just this has put me on edge. He is 38 and she is 20 I am 30 just.
