First meetings with partners kids

[Sosad7700]

I’ve been dating a man with two kids for a year . His ex has been with someone for four years . They share 50/50 custody . I have no kids of my own . I have met the kids a few times , but they dont seem very happy to see me . When I said good bye to them last time, they didn’t even look at me. I mentioned my upset to my other half and he was offended and said ‘don’t have a go at my kids ‘. Is this normal / does this get better ? They seem to have accepted their mums partner no problem .
Thanks

I'd give it a bit longer to see if anything changes but if it doesn't improve I'd call it off.

I've hated a step parent and it was miserable for me and probably for him (but he was a dick).

I really couldn't be in a relationship with someone whose kids didn't like me. Actually after being on mumsnet and seeing other friends experiences, I don't think I'd ever get together with someone with kids.

In my experience meeting my partners children it takes a while for them to warm up and feel comfortable with you.
However; your partners reaction to you approaching him re their rudeness would bother me. It's polite and manners cost nothing to say hello and goodbye. He should have picked up on it and made them be pleasant or at least acknowledged and apologised on their behalf this time.
If he is defensive at this, it will get worse - trust me.
