Mate, you already know what to do!
If your chick is going OS without you or you don't feel welcome it's time to say goodbye.
Any woman that has other numbers, flirts or disrespects you in any way is not worth the trouble.
Find a lady that likes you and no one else. Find a family that likes you and wants you to be part of their family.
Get some balls, standup and don't take so much crap from people.
Do you have alcohol or drug problems? (If so get help) Do you have a job? (If not get off your arse)
Most Mother-In-Laws have a very good understanding of blokes. She doesn't like you because there are reasons!
Analyse your self, try not to worry though, just improve what you can to your standards not other peoples.
You only get one shot at life, so be happy, shrug off **** that isn't for you or doesn't work.
Get rid of this woman, have a break, have some fun, and start saying no.
PS: There's plenty of hot shiellas in Perth. :thumbsup:
