I am not sure about the fight, maybe you could ask if he wasn’t planning on staying long.

But the whole thing seems a bit off. Regardless of pandemics not going anywhere together for 16 months is unusual. Plenty of things are open. Even if you live in the area/country where everything is locked up, you could do outdoors activities/outdoors venues etc I find it curious that you two don’t do that.

Just going to each other house might be ok, but not if he just watches football and you do your own thing. If a man just wants to come to my house to watch football, he could stay in his own house. He can’t go anywhere with you but he manages to come over. I’ve met guys like this sadly. Is he coming over to just have sex? It doesn’t sound like he comes over to do anything else. Have meaningful conversations with you? Play board games? Cook together? Put puzzles together? Go for walks in the neighborhood?

Did he ever express how he sees this relationship progressing? Are you two in love?
