Moving in with friend who won’t let my kids dad in the house

I have two kids, 4 and 3. Their dad and I coparent very well and get along great for the most part.

I’m getting ready to move and on my of my really good friends (who doesn’t have any kids) brought up the idea of renting a big house together so we could both have more room and live in a nice neighborhood. I agreed.

She came over to my place this weekend and kind of hit me out of nowhere with her “ground rules”. She said when we have our place that my kids dad won’t be welcome inside our house at all because she doesn’t know him and doesn’t care to get to know him. That him being in the house would make her uncomfortable so if my kids want to see him it has to be outside the house. Like I said, my kids’ dad and I are in great terms and we all hang out together at ky current place a lot. Eat dinner, watch movies or whatever and then he goes home. He’ll also come in to chat when he drops the off at the end of the weekend. I guess my question is, should I accept my friends ground rule and just forego that or is she asking a little too much? I asked if she would like to get together with him so she could meet him and see he’s a good guy but she refused. She also implied if I start dating anyone they won’t be welcome in the house either. I don’t know some of her close people that well but I wouldn’t stop them coming over. Advice would be appreciated before I sign a lease with this person I need to know if I’m over reacting in being a little taken aback by this lol.

I just know my kids will be bummed if their dad can’t come over at all ever.
