Long but PLEASE read and help!!

So my boyfriend and I have been together for almost 3 years and we just recently had a soon together last month (unplanned but best thing that’s ever happened to me). Anyways the first year or our relationship was great! I felt like I met the best friend that I didn’t know I needed. We have so much in common yet we’re opposites in personality.

We used to have so much fun together and go on random dates just because, try new things together, actually have deep conversations etc.. Right before meeting him I had gotten out of a toxic 4 year long, off and on relationship with my ex and I never felt secure with him in the sense that I was enough to keep him happy but when I met my current boyfriend there was no doubt.

Now only a little more than 2.5 years into the relationship everything is meh... We barely talk anymore unless it’s about anime (we’re huge anime freaks so I don’t mind that), I can’t even remember when’s the last time we went out on a date, he’s super secretive but kinda always has been but it bothers me still and he would literally do anything so he won’t have to spend time with me (or so that’s how I feel). For example he’ll stay after work 2-3 hours talking to his coworkers about the same thing (so he told me) instead of coming home. Or he’ll go randomly help people clean up or whatever they need but then doesn’t clean anything around the apartment. Basically I’m bored in this relationship and I feel like we’re roommates instead of partners.

I’ve had several (like more than 4 times) talks about how I want to do more things together instead of always sitting in the house watching tv or playing the game and he’s like ok but things haven’t changed even for little. I ask him is he happy is there anything I can do to make things better and he acts like things are peachy and always says no. I even threatened to leave if things didn’t change, get better but thought those were the pregnancy hormones talking. Now I don’t think it was because I feel the same way still. I know I still love him and I don’t want to break up but somethings gotta give. So what can or should I do? Any advice?

I’m fully prepared to coparent but I would much rather our relationship work out especially since I’d have to move back home to a different state if we break up.
