partner has got very friendly with a new school mum. she is friendly with me also but not as much as with my man. she is single and has him round to do diy for her and have coffee and he can be gone for quite some time while i am left at home with my little ones. am i being paranoid to think there is more to this relationship? how do i approach the subject without sounding like i am a jealous cow? am so confused as i'm not really a jealous type( which is now making my mind go crazy as i wonder if its a sixth sense), but my man is and i know this would cause huge arguments if the 'shoe was on the other foot'!
