Dating advice

Ok so I'm recently divorced trying to get back into dating game. I NEED SOME ADVICE! So this guy hits me up asking if I want to grab a beer sometime. I say yes and give him my number. That was A MONTH AGO! In that month, I have hit him up many times trying to set up this date. He always seems to be "busy" or says he has to work in the morning. I'm trying to be patient and not read to far into it but I'm starting to think I should give up. Seems like even though he asked me out, he isn't interested all the sudden. Does this seem wierd to you ladies? Should I move on to the next fella?
