The OP is better off leaving this guy... as she doesn't understand men, their passions, or even people in general. Actually... it would be best if she doesn't date at all until she gets over her phobia of any man being a potential cheater. She's just going to encourage her paranoia and drive any man she's with nuts (and not in a good way).
To the OP... stop being manipulative on the forum... your efforts are transparent... we see this every day.
Why not be straight forward? You fear being cheated on... this guy has a passion for music... you have no say on how he spends his money... you like to score keep (relationships aren't games... so whoever has the most 'points' isn't going win a damn thing)... money means a lot to you... and you're terrible at problem-solving (didn't resolve your problem from the last relationship... and ready to take on a new relationship with new potential problems?).
The only problem I see in this relationship thus far is YOU. You're still healing from the last broken heart you had... and rather than being mature about it and SOLVING it... you'd rather bad-mouth this guy... insinuate that any man could be bad news... and cry about how you're the 'victim.'
Be a big girl... fix your problems before jumping into another relationship. I guarantee you'll have far more success...
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
