Is he not interested?

Been talking to a guy for a while and starting to feel like I'm wasting my time waiting for him to make a move. He says he's interested but hasn't asked me out yet and honestly I'm losing interest. He's a nice guy and we talk everyday but it's been over a month and he hasn't asked me out yet. Said he's waiting for the right time. How is it not the right time after a month of talking? I'm 31 and he's 33 so we aren't young and I've never had a guy wait this long to ask me out. He's the only guy I've been talking to (we met online) and now I just feel like I wasted my time on him. He knows everything about me and my life so I think it's definitely time to go to the next step but I feel like it's pointless at this time and I should move on but I really do like him. He doesn't talk about sex or ask me for dirty sexy or dirty pictures which is nice for once but I'm lost on what I should do. Should I assume he's not that interested and move on?
