don't know what to do

K
I've been with my boyfriend for a year and a half and we've lived together for 6 months. This past week I've been worried that we're not going to last. The main reason being we have different world views (we agree on most general things but there are some things extremely important to me that he doesn't agree with). I also am extremely into politics and human rights activism, it's basically at the core of my being, and he's not, and he has said I'm too much of a liberal lol. He's never tried to tone me down or whatever, but yeah.. I've been worried about this for a long time. But it's hard to tell what's truly a gut feeling and what's just my anxiety putting me into fight or flight mode. This is my first relationship and he's the only person I've ever loved romantically (I'm 23). He's a great boyfriend, I feel loved and safe with him, but I get mad a lot-usually because he says something I don't like that all comes back to our different world views. It's hard to explain. So I'm not sure what to do. I love him so much and I'm happy with him for the most part but I also don't want to waste my or his time if I don't believe deep down we're going to last. Our lease is up in 6 months and I feel that I shouldn't move together again if I'm not sure about us. Then I'm like am I just stressed because we got a new puppy and I woke up in a bad mood today? lol. Help me 😣
