Is he really that busy ?? 10pts?

Okay I been talking to this man for about a month now. We met on the bus cause he drives the bus . At first I wasent interested but then I said I will give him a chance. Now mind you im 22 and he is 55. I know it's a big age difference but I figured I try something new . Okay. He works from 4am to 5 pm and lives an hour away from his home . I work overnight. My problem is I get he's busy with work I understand that. But you mean to tell me you can't call or text me at all ??? The only time he will txt is if i text him. Then he might txt back. He goes on break and never calls or txts. He would always say we can meet this time but then always has some type of excuse. We talked about him knowing I need attentions and that he likes me but he's always busy from work. which I understood. But what's really starting to get under my skin is the fact that when we see each other on the bus he's all up on me. Telling me he wanna make love to me and so on. But then I don't hear from him till the next time I work. Mind you he's off on weekends and im off every other weekend . Should I just leave his *** alone ?? . I do like the man cause he is nice but he's not giving me attention that I want. He's supposed to be trying but ain't trying hard enough.
