Is it bad that i'm dating someone new but still stalk my ex on social media?

or actually still think about my ex every single day..

we talked three days ago after two months of no contact. i meet someone new during those two months (we're broken up last year but had an on and off contact). i messaged him to clear the air and he basically found out there's someone new. he said its a good thing i he knows because it became a sign for him that we're officially over. i was the one who left him but i never lost feelings for him. our texts became a call that lasted about two hours. i ended up crying. i told the new guy im dating that i talked with my ex but all he knows is that i did it to clear the air. my ex and i talked about a lot of stuff and one of those is saying the right thing to do is not talk anymore at all. which was right. i like the new guy im dating but thats just it, its new, so the feelings of course is not as real as i have for my ex.
