It seems like we want different things

I'll probably delete this later but I need to vent. It feels like my husband and I care about different things, drastically different. He is still kind of young in the mind. I don't see him as a leader or very goal-oriented.

Lately all that I've been hoping for, thinking about, and working towards is growing our family as well as fixing up our apartment. I'm constantly having creative ideas for the walls and floors and how our space could be re-designed, and also looking into house plans to build our own in the future and I'm saving for this stuff. I include him in these things but he usually tells me I can do what I want with our space since he's laid back and happy with whatever. And I've been tracking bbt, taking good vitamins, and eating healthier in general, as we've been trying TTC for 8 months. I'm very focused on getting pregnant.

Meanwhile it seems like all he cares about is video games, weed, and secretly watching porn. Which he tries to hide from me but I always find out somehow. Porn has been a huge negative thing in our relationship. I am so hurt from him watching it. I'm starting to think he has an addiction because he always goes back to it no matter what we discuss.

Anyway, it seems like he doesn't care to actually put effort into our future and make something for ourselves. Like he just cares about instant pleasure, things he can do immediately to be entertained and feel good. I feel like he's still a teenager and I'm the actual adult here. We are both still in our early 20s but I'm not sure if that's relevant. It just gets to me, especially lately it's been more prominent in my mind.

Idk if I want advice or support or encouragement. I'm just sad and needed to get it off my chest.
