I (30F) think I am getting stuck in a situationship with the guy (30M) I am seeing and don't know how to have a conversation about being exclusive with him or just to end it because of some red flags I recently found.

I (30F) have been seeing this guy (30M) for a few months now. At the start of us dating I had ended things after I think date 3 because he was acting sneaky and deceiving. I had a feeling that I couldn't trust him. A month or so later he turns up as one of my new coworkers and texts me asking how I wanted to handle things. We started being friends and then 'dating" again. There are quotes around dating because we have only actually been in three normal dates. The rest of the time we hang out watch shows and end up being intimate. His sneaky and deceiving behavior disappeared for the first few weeks but I have definitely noticed it again. Not only on different social media platforms, does he follow and like a ton of different girls photos that are notched the most appropriate. But he has also scheduled dates with me three times and completely forgot about them. Even when I bring them up. He acts as if we already did them. Then he recently tried to confirm other plans with me for a weekend and stumbled over his words and I think he had plans with another girl because he got really jumbled. There have also been a couple times where he thinks he shared a story or podcast with me but didn't and is stubborn enough to argue that point with me. The latest thing I noticed is he befriended a girl at work who participates in his football team somehow on the weekends. She seems to promote the team somehow I'm not sure if this is relevant though. I am starting to feel as though it's not worth the trouble. I feel as though at this point I am just a booty call to him. So I wanted to get some opinions on whether I should even attempt a conversation with him or just end it? It doesn't bother me that I still work with him. I can be professional at work.
