I was playing an online game. One random opponent kept inviting me for repeat games. He invited me to chat. From my profile name my gender is obvious, but I did not see any issue at that stage. Since his game was good I agreed. Neither party is single and I am certainly not looking for anything, but heck, can one not even talk without assumptions being made?
I found him a bit too intense but blamed that on cultural differences (he’s in the US). Except that yesterday he sent me an ‘innocuous’ greeting (‘good afternoon’) with a selfie of him, admittedly clothed, on the edge of an evidently rumpled bed. After that I just blocked him everywhere. Was that unreasonable?
