This sentence is a run-on and doesn't really make sense. "until now whether we go against them we haven't caught up with them even once it's our losing pattern" If proofreading I might edit it like this: "Until now, We haven't caught up with them even once. Whether or not we go against them, it's a losing pattern." Not knowing the context is really confusing. I would assume that this person is fighting another person or group, but they cannot win?
