I've lived with my now ex for four years, and we've not got kids together. I found messages on his phone that he had sent to women from hook up sites when he way away with work, giving them the name of his hotel and asking them to come round. I confronted him and he said he was drunk and horny but did not actually sleep with anyone or meet anyone. Whether he did or didn't, I ended the relationship, not only for that but for various issues like us just not being compatible together anymore. When the lockdown ends I will be moving out of the area. He is creeping around me at the moment asking me whether I want him to make me a cup of tea, even though he is in agreement we should split. I know it's the "grown up" thing to do to be nice but I feel like telling him to fuck off and I don't need his pity. I know this makes the relationship sound terrible, but there was at one point a lot of love, and I don't know if I should go completely no contact (which is tempting) or whether if I do this I will later look back and regret not trying to maintain a friendship? To me right now maintaining any sort of relationship seems frankly undignified, and my gut is telling me to go ahead and block his number. But I'm angry so it could be that. Advice???
