@ritamoyochief,
The age difference isn't necessarily a killer, but I don't like his not showing up for scheduled dates. That would be okay sometimes, since things do come up, but you are entitled to at least a phone call and an apology.
I'm not too keen on the whole thing because I expect his schedule will continue to have a higher priority than you. There may be perfectly good reasons for this, but in your place, I just wouldn't like it.
