Rude or not

I am in a LDR (long distance relationship) and I haven't seen my boyfriend in 3 months.

So I asked to come and see him this weekend and he said no my kids are gonna be here. So I was confused because I've gone and seen him when the kids were there and I've met them and all. So I asked why not (not in a rudeway)

And he said quote on quote: "If you come I'll just ignore you because I don't have time for you and I'd rather give my attention to my kids"

(Please note I'm fully aware his kids are his priority)

But that aside, is this Rude? Yes or no
