Ok guys so this is a bit complicated. Me and my OH been together 3 years and have a beautiful 1 year old daughter. He was previously married and has a son with ex wife. Since me and him got together they been separated for 4 years. I have a very good connection with his son. Since me and OH have been together his ex has been making my life a misery. She's been texting him saying I'm trying to poison her son because he has diarreha from my food (the same night he had chicken for dinner at her house), she's been calling me fat( even though I'm 56kg) she's been calling him names and texting at freaking 3am with stupid talks about how he should give her more money for her son etc. Lately everything had calm down. We've set up a child maintenance payments so that she gets the amount she should and not spend it on herself but on the kid( we also buy him anything he asks for). And for past 2 months she has been calling him and talking all nice like "What paint should I use on the walls" or how is my and his dog doing?! So I said to my OH I do not want her being all f* nice after all that and so that she calls regarding their son and nothing else, he said sure that's ok, but today he received a weird message from her while he was in the shower so I opened and had a look. In the watsapp conversation I found him sending her pictures of our dog with captions like "look she's scared to walk in the forest" etc and her sending him pictures of her old dog and videos and a spinning to send some videos of our dog?!?!??! I don't know what the heck that is about, but it hurts me has been all lovely talking to her behind my back not about their son but different things. What should I think of this? I'm actually fuming right now!
