Partner and i have been having problems so I start ...

You obviously know what to do but you must build up your courage to do it and that is to leave him as soon as possible. The fact that he relies on all these stimulating devices such as girlei magazines shows that he includes you as one of his stimulants. Your dependency on him because you are between jobs just enforces his power over you. It will be difficult, but leave him. You will better off despite the economic hurt but you will regain your self respect that he has taken from you.

Good Luck!! 

you need to leave him relationships are built on trust and honesty not lies

First Porn mags by themselves don't destroy a good relationship, so there is more to it than that. Next chill, bide your time and start planning because you need a roof over your head for the time being. Don't start any arguments or confront him about the mags. It may take a while before you get a job..the job market is pitiful right about now. At some point you will return to work, try to make sure your probationary period is up. Then announce your plans and move out and on with your life..good luck.

Well who doesn't have porn.. I don't think that's so bad.. To each his own.. Did u find out whose # it was? Maybe it was nothing.. Your BF may be cold becuz he's embarrassed about his porn..he didn't expect that kind of reaction from you.. try talking to him.. if that doesn't work.. wait until you get a  stable job and then move.. try to save as much as possible now.. maybe you can stay with some family if it gets too bad.. Hope everything works out!!  Good Luck
