Feeling Rejected

So sorry to hear this, it must be incredibly difficult for you. Guys who struggle with this tend to be on a spectrum ranging from the guys who hate the habit and are secretive and ashamed (these guys confess and embrace change usually as soon as they get caught) and then those guys who are more brazen about it (these guys often have consciously chosen P as part of their lifestyle and aren't prepared to change).

As you know, any hope for a future starts with a change of heart - even if change of behavior is a slow process.

There are many partners of P addicts here, like @fupornwife who can advise you, but my 5c worth is that he needs a strong wake-up call. He evidently believes he can keep the habit and keep you. For the sake of a future, I suggest you contemplate giving him an ultimatum, and being willing to follow through on it (e.g. Move out if necessary).

The hope is that this brings him to his senses.

Whatever you choose, just remember that this addiction escalates over time, so co-existing with it is going to bring more pain.

I honesty hope and pray that the penny drops for him that he's being an utter fool.

Godspeed
