SO is no fun😩 (Venting)

So I'm 22 years old and he is 28. We have been together for almost a year and a half and he has 2 kids from previous relationship. And he's just no fun! We never do anything. He works in another city now and we only see each other during the weekend. And all he wants to do is have sex! We don't live together so we get a hotel. And it's getting annoying. I understand he wants to work hard for his kids and all but what about me? I feel like I'm missing out in so many things! And I think there's nothing better than doing those things with him but he just doesn't want to.😪 I want us to have our time before starting a family ourselves. I love him and I feel like I'm always there supporting his decision but he just won't do anything for me. I don't even get exited about weekends because I already know what's going to happen.
