It’s hard to tell from what you’ve revealed, what’s really going on.
How did you ruin his business? And how were you obsessive enough for him to break up with you?
How long were you dating before the breakup?
From what you meagerly describe, above, it does sound like he isn’t physically attracted to you as much as he once was. It’s hard to tell from the little you’ve written whether he’s still upset about what transpired between you two that led to the break up, or whether there may be someone else in his life, as well as you.
It’s also hard to tell if when he said your physical appearance was just “ok”, it was because that’s what he really felt or because you were fishing so hard for compliments that he was turned off by your desire to appreciated.
So, let me know more, and I can help you better. 🙂
