My ex and I split up for the final time recently. We have a 5 month old son. He had never been very supportive despite our child being planned and him appearing to his large family like he’s super dad. He has been going out drinking multiple times in the week, out until the early hours and I finally kicked him out when I discovered he used cocaine. My MIL has always been overly involved in my opinion. During my 3 day labour my ex called her to take a shift sitting with me so he could sleep in her car. She was the one there when I found out I needed an emergency c. After my son was born she FaceTimed daily and attempts to see him every day (she’ll text and say I’ll pop in and see him on the way back if he’s awake). She also has an 11 year old daughter. When they come over I constantly feel undermined. For example, she’s been nagging me to wean my child since he was 4 months old and told my ex I can’t moan about not getting sleep if I won’t put him on solids. Also my ex and I decided relatives kissing our child is a hard no. The other day they came over and her child was covered in facepaint. She was all over my son, holding him up to her face, kissing him, leaning over him, shouting in his face, forcing toys into his mouth and I bit my tongue. I also bit my tongue when his mum offered him her finger to chew without washing her hands and despite coming from a day out. I didn’t say anything but when my ex came over I already had an attitude with him about the fact he’d been out the night before and had the whole day off with a hangover (a day which in my opinion he could of spent seeing his son). In the course of the argument I angrily told him to tell his mum to stop kissing the baby, that every day is too much to see him and not to FaceTime after 6. He then messaged when he left saying she was now uncomfortable and that he wants to take my 5 month old baby (EBF never been without me) out by himself for 2 hours a week so his mum can see him. I messaged her trying to make amends and she not only ignored it but blocked me. Since then my ex (who only last week messaged me to say he liked the way our son is being raised) has said I’m a bad Mum because I stay cooped up in the flat and don’t take our son out enough and that I’m a hypochondriac because I’ve dared say he has a cold again. Am I being unreasonable?
