Tenancy Agreement With Break Clause

If she wants to stay and I want to leave, can`t I leave the lease and I`m stuck with someone who doesn`t want to accept that we`re the same in the contract? I read on the Internet that in case of joint rental, agencies or landlords expect us to solve our own problems, but the only solution to this problem is the breaking of the lease and separate rental. Should I involve the Agency and inform it of these recurring problems and ask them to take action? I wouldn`t mind being removed from the contract as long as I get my share of the deposit back, but if I leave, I doubt she will return the money to me immediately because of her money problems – the lease clearly states that if one tenant leaves, the other must repay him the deposit`s share. .
