This may sound really petty , but I think my mil is trying to get my dh to look at other women. She started hanging about with younger people about 5 years ago not long after our 1st child. When I say younger people i mean 18-25 year olds mainly her friends kids. She talks about them a lot and always makes a big huge fuss over them on there birthdays etc referring to them her good friends. It’s cringeworthy. But I can’t help but feel she wants me to be jealous of them because they have good careers and they are young and free. Always harps on about how beautiful ( they are models ) they are and how dh should work with them etc ( they have professions similar) it’s caused many an argument in our home and it’s left me feeling horrible and insecure. DH thinks I’m over reacting. I’ve already told him that I think it’s really weird and ask him how would he like it ?! This all seem to come about around the time we got married. Hoards of strangers were suddenly in her life and it became very chaotic ... my sister in law feels the same too. Although we tend not to talk about it too much as we both feel guilty. Also DH will not comment when I say anything which bothers me even more , he even commented once that said girl looked like me when I was younger 
why would I want that while I feel post baby fat. He denies this now when I ask him. It just makes me mad that these random people are in our line of view .... and yes most of this public affection from his mother goes on on fb ... she even shares her friendship with one of them as her “ life events” on fb , not her grandchildren being born or son being married a friendship with a girl a quarter of her age. It’s turning me into a not very nice person I’ve started to very self conscious over it all - even considering Botox as I feel like I’m being compared. Am I being petty or am I well within my rights?
