27/f and 45/m - Is this the start of a controlling relationship?

I 27f and my coworker 45m have worked together closely for the past 2 months, before that we worked in separate areas. So after getting to know each other and found there was mutual attraction he came over to my place and hung out for a couple hours. Since then he’s been very persistent on coming over to hang out, he does have 2 kids so I understand that it’s not easy for him to always get away. It’s happened twice now where we make plans to hang out and he ends up “falling asleep” or it just gets too late for him. Through text messages he’s been telling me he can’t stop thinking about me and that he can’t wait to figure out each others likes and dislikes. Now, in a separate conversation we had prior to him coming over to my place we both had stated that we liked being single and we both are not looking for a relationship, just fun. Now he is being completely different and using phrases like “your other house” “our bed” “When you want, my world can become your world” Also mentioned about me meeting his ex wife, mind you he came over on Monday so we’ve only been talking for about a week. I’m not sure if this is what the term love bombing is, as i’ve only been in one relationship and that lasted 7 years. So the way he is talking is completely new to me and i’m not familiar with it . I also don’t know if maybe that’s just how an older guy is? He tells me he can’t stop thinking about me since seeing each other last Monday. He can’t get me out of his mind. It’s hard to tell if he is being genuine with me or not since on two occasions now he’s flaked on plans. I’m actually confused and i’m not sure what he wants from me? He makes it clear what he wants, but it’s the way he says things that makes me feel like it’s just moving way too fast since we’ve only had one on one time outside of work for MAYBE 5 hours. I’m just wanting to see what other people think of the situation and if this is the start of a controlling type of relationship? He’s told me that he’s a super jealous person and that he walks by my machine to let me know he’s thinking about me or just to make eye contact, since we’re keeping things private about our situation. So I can’t really talk to anyone that knows him at work since it would break trust between us. Please give me advice or if you’ve been through anything similar? TIA
