Do you think I should stay or leave?

I've been with my boyfriend for 8 years. We are both in our 40s. My problem is I'm getting tired and fed up. This guy parties every single weekend faithfully. I don't see him slowing down. He goes see his ex girlfriend and her kids every Saturday. ( they are not his kids). In the last 8 years I've never met them. When I ask about meeting them all he says is that it's not up to him. Meanwhile the ex has me blocked on Facebook. Another problem I have is that when he's home he is always on his phone chatting with other people on social media. When I bring it up all he says is that it's his phone and he pays for it. There is hardly any communication between us. Don't get me wrong he does treat me good but I can't deal with all of this. Am I being selfish?
