(Sorry for formatting, am on mobile) This morning, I (F22) woke up to my boyfriend (M34) masturbating to porn online. I had woken up multiple times throughout the night to him jerking off, closing my eyes and hoping it wasn't real. This has been the third consecutive night he has done this, and I finally built the courage to confront him about it this morning. He retaliated at first after I told him this was an immense deal breaker in our relationship. We used to have sex two or three times each day in the beginning of our relationship, but despite my advances, it has fizzled to one every other day or so. He told me that his decreased sex drive has nothing to do with me, and that I'm just letting my insecurities get the best of me. He hasn't told me if or how he will change, but I made it clear that I want nothing to do with him if he is so dependent on porn. I feel so worthless, shameful, and ugly due to his usage. I am about to leave, but I want to know if I should give him a chance to turn around before I do so.
