That awkward time

Well, I will get straight to the situation & perhaps someone will help me out on this matter. A former girlfriend will not permit my attending the same dance venue that she attends regularly, telling me that if I were to appear it would make her feel "awkward" amongst her friends. We "split" on good terms but I can't understand why she thinks that she can exclude me from a public venue. I don't want to make her feel awkward but I have always held to the "ethos" that the basic success principle underlying all manners is to think about other people's feelings first because it is still not all about me. If I "sacrifice" myself to respect her wishes & feelings in this instance, then I am respecting her. But she does not seem to respect my feelings & the right that I have to attend a public venue despite her potentially being "awkward" if I did attend. I am not a confident person to begin with & this situation is lowering my confidence level to a negative state even further. I do wish to respect her feelings but am I to do this by sacrificing my own self-respect...even if there were any at this point? My confidence now is utterly annihilated!
