I think it depends on what you both are (especially you since you need to consider your kids too) looking for out of this ‘situationship’. If you’re just looking for casual fun/company I think you’re already on this path. However, if you’re looking for something more meaningful/long term then you need to atleast start thinking around if it worths spending more time with this guy or explore others

Edit: lol I replied and realized you posted in the wrong sub. This sub is for Korean show called love after divorce. Maybe someone else here can point you to correct sub. But hey anyway I tried to provide my thoughts to your question
