Pandemic relationships

I’ve been dating a guy for almost two years.

We are living together for 6 moths and we are both working from home.

Because of pandemic our social life is very limited and I do not have friends or any family around because I live very far from my country.

Last night he told me he’s very tired of seeing only me 24 hrs a day, which was a shock for me as I thought things were ok, we never fought or even argued about anything.

I’m so confused with his signals after what he said and wondering how other people are dealing with their partners locked at home.

Am I the problem?
