Do you think if you suggest doing some activities together for the baby-like walking in a park/having a picnic/going to the zoo etc-he would go and might enjoy your company while doing things together as a family?

I’ve tried to make time. I do family time he’s on his phone. We go out for walks with the baby by ourselves he doesn’t engage. We spoke about a paint class a cooking class salsa classes and he said yes but now it’s a no. He’s hot and cold and lately it’s been cold and it doesn’t seem like it matters anymore to him. I want to try and if we try and it doesn’t work then at least I know we tried. But he’s not budging
