Am I being used?

Brielle
This guy I've been seeing for the past 8 months seemed like he would be the perfect guy for me at first. He's older, very successful, wealthy, and the sex was great. However, things have not really been progressing and I'm getting frustrated. He won't introduce me to his family bc we have a 14 year age difference. He won't even agree to meet mine even though my parents are totally supportive. He won't take me out on dates. We don't get to see each other very much bc he claims he's too busy with his business. I've complained to him about all of this but nothing seems to change. I'm beginning to feel used and I feel more alone than I do when I'm single. Should I just give up? This is the second guy who seemed to not want me and I'm not trying to start all over again.
