Smart of you to cancel a date. If he wanted to keep his options open, it’s fine, but then no need to sleep together. I am glad you had that discussion and were direct. It’s always better to ask directly. Now you know what’s going on. Personally I think stopping seeing him all together might be a good idea. If you are looking for “the one”, he likely isn’t “it”. But if you want to continue seeing him, keep it low key and see others.

I’d stop sleeping with him though. I know you said you are ok having casual sex without exclusively and you fell liberated but deep inside I think it’s just disrespectful and rude to sleep with a woman while talking to other women on dating sites.

You deserve better than that. Congratulations on addressing it and finding out early on. You did the right thing!
