Trying to convince the gf to stop smoking

[Tom]

Thanks for all the input everyone it really has helped my depressing evening, but shes been out drinking running her mouth now so im properly f*cked off, found out shes lied to me about 3 times this evening aswell, then its my fault when i cant trust her... man relationships are such hard work, the emotional strain is almost unbearable.. im going bed before i kill someone
