Guy I’m dating shows up and walks in my house unannounced while my kids are there , acceptable or not?

I’m dating a guy for nearly a year now

We both have kids , separate houses but we stay over each other’s houses and the kids know us

This week he has shown up unannounced twice and walked in the house, the first time he rang me and asked me where I was in my house , the second time I wasn’t home as I went to my friend who wanted me to come over so she could talk to me

Then second time my eldest daughter who is 17 told him this and that it was weird and he shouldn’t do that He said your mum did it to me to which she replied no she doesn’t and I have never done it as I would find it lacking respect especially when there is kids involved

He now is angry says that he can’t be in a relationship with me because I don’t communicate with him I told him I didn’t know I was going to see her and if I knew he was going to come over I would have been at home

We work together and this is going to be extremely difficult to deal with

Any advice and thoughts on this please?
