Honestly is this relationship worth saving? Sounds like you two are very different in your values and have different ideas about commitment. Maybe it's better to find someone who is more compatible with you. From what you wrote here it sounds like you are trying to make something work that isn't working.
I say let her go. Find a girl who isn't into going out all the time and someone who you feel you can trust. She needs to find someone who is okay with her doing that. Both of you can be happy, but maybe just not with each other.

So why are you hanging on? you gotta have a reason why you are still holding on to her and taking all that crap. Why? You afraid to go back to being single? afraid you won't get another girl?
Once trust is gone, homie, the countdown to self-destruct has already begun, you can try to delay it but its inevitable. So leave now.
Also you do sound a bit controlling, though. Just letting you know.
