Yesterday my SO's dad said some mean things about me. So, this morning his dad texted me askimg me if my SO was ok. I texted him back what do you mean? Then explained he went to work. His dad called me and told me if he was Fred (my SO) he would leave me. I'm disgusting, my house is always a mess and my baby always smells like puke and fred shouldn't have to come home from work to cook and clean for me. I didn't even know what to say. I called my SO in tears. He was at work and he knew right away what his dad had said to me because he texted him telling him I was a piece of shit girlfriend and mother and he was bad mouthing me yesterday. So, yesterday Fred comes home from working with his brother and says to me that his dad was talking garbage about his mom who committed suicide August 2017 in their home. When his dad was actually talking about me. I am constantly cleaning. I have a 9 year old and a 6 month old. My 9 year old has down syndrome and has a hard time cleaning up after herself. I'm constantly reminding her that she needs to pick up her toys. Saturdays, I do all my deep cleaning. I bleach the floors and counters monthly I bleach the walls. I rarely have dishes in my sink as I have a dishwasher. There is clutter on our kitchen table from when my SO comes home and puts stuff on the table. I don't touch his stuff just in case he needs something and I misplace it. He puts his stuff away or lack of. As for the baby... She's 6 months old, has reflux and is always spitting up or drooling as she's teething too. I give her a bath every other day sometimes 3 times a week and am constantly wiping her down because she pukes so much. Oh and I do majority of the cooking just to make that clear unless it grilled food because he's way better at it. I'm also still battling postpartum depression and I have really bad anxiety. This has been eating at me all day and I can't stop thinking about it. Like I've been in tears all day over this. Maybe I'm overthinking but I've never done anything to his dad for him to say those awful things to me.

What do I do? This is my child's grandfather and at this point I don't want him in my home at all. He was wrong on so many levels and I'm really feeling hurt.
