Coworker mess 🙄

The guy I’ve liked told me from the start he wanted nothing serious just casual hookups.I told him that might not be the best idea for me because I tend to get attached to people easily.He respected that and we agreed to just be friends ( we spend a lot of time together as we work 40 hours a week together, works been fine not awkward for me atleast but he is really flirty at work when no one’s around) so I haven’t hooked up with him but now he’s been texting me all the time everyday flirting with me and sent me some social media post about how when you’ve found the right person you will want to be around them all the time and about how strong of a connection their is with that person.So I’m just confused he is sending me mixed signals..I am assuming he is doing all this to try to get in my pants though.
