If you have a partner like cuppatea has described then get out quick.However if he is not like this, and you want to stay with him, then try not to seek restitution. I know it's hard because you've got a certain view of how you want an apology to look, how his 'trying' should look and how love should look. But the past is done. You're either choosing to move on with him or you're not. When you're thinking about restitution and how you expect him to behave try to remember that we're all human and we make mistakes. Even if it seems ridiculous that he would jeopardise everything for porn try to have compassion for the human aspect of all of this. Also I'm sure you do plenty of loving things to try to build your emotional connection, but instead of being disappointed that he hasn't written you a love post-it write him one. Also if you haven't already done so it may be useful for both of you to do the love languages quiz so each of you knows how the other best receives love. I can post you a link if you haven't seen it before. The more you think about what things he should be saying or doing to make it up to you the more time you're wasting. So although you feel valuable time has been wasted with his addiction, it's also being wasted now. I say this as someone who has left my marriage; the damage to my self esteem was too great for me, it was to the point where if he would make advances I didn't feel they were sincere even though they probably were. So I'm not saying stay with your partner, I'm just saying if you're staying then focus on the present and the only thing you can control- your actions.
"Mistake- an act or judgment that is misguided or wrong." I didn't say "accidents", I said "mistakes". Yes, years of bloody big mistakes in most cases, all of which involved choice.
I totally understand how you're feeling. So what's your next move if you're not getting what you need? I know that I wasted a lot of time in a previous relationship trying to make it work with a man who was physically, sexually and emotionally abusive and very controlling (prior to my husband). I kept thinking if I just do this or that differently then maybe it'll get better. I was also worried that I wouldn't find someone as good, which sounds ridiculous now.You know you could find someone who would treat you better, so whar's keeping you there? Is it your children? Your commitment to your marriage? Or something more? Are there signs that he'll be able to make it up to you? That he'll be a better partner, the kind you need? I suppose I'm going at it from these two angles of stay or go because I don't know how to make someone truly understand and make up for the ways they've hurt you. They either get it or they don't. I'm sure you've told him plenty of times so what more can you do?
