3 years? jesus christ man…I wouldn’t let that bullshit go on for more than a week or so. When you’re with her and she gets that restricted phone call, grab her fucking phone and confront him, tell him to cut his shit, and go find his own pussy instead of feeding off your scraps. This approach would backfire of course if she is in fact banging him on the side. Be sure to ask her why she isn’t doing anything about this, and if she doesn’t give a straight up answer, she’s just enjoying the attention like 99.9999% of all women do. And don’t forget, yelling is good. Yelling and/or losing your temper gets your point across when need be.
