Why Is He Acting Like This With Me?

So there is a guy with whom I worked couple months ago that only asks me for a date when it is very late at night.I thought he liked me because he complimented me and told that he thinks I am sexy but I don't think he is serious I think he is only messing with me. I said to him more than once that I only wanna go out with him when it isn't that late, not in the evening and he says ok but when we have to meet that day he says he can't anymore to go out with me. Yesterday we should have met and drink a coffee together and I waited for him the entire day to call so I messaged him eventually. He said he isn't available. I felt really stupid that I have trusted him. When he calls me he says only bullshit that oh he is very sincere and devoted in a relationship and he would like to know me better but when we actually have to go out he doesn't call anymore. Why would a guy at 28 year old would do that if he isn't interested in a woman?
During the quarantine he even asked if we could meet at my home but considering the fact that he is almost a stranger and I don't trust in him I refused him. I really don't know if he want me only for sex or is a pathological liar with mental issues.
I feel really naive to think that he was really interested in me. The thing is that I never had a boyfriend before, it is not that shocking actually that at 25 years old I never been with a man, because my parents were very strict and now I feel the lack of a man in my life.
I really thought he would actually be attracted to me.but apparently not, I actually feel really pathetic, I don't think he knows I am a virgin he may think I am stupid I am not good at all at reading men. :(
