@Katzuba,
I think that you have out-grown this person. You were prepared to accept initially that love is exactly that. And, it is.
But you are a grown woman now that has more needs and desires in life. One being that you want an equal partner perhaps, one when you both get home from work can converse over the day as well as have interesting conversations and dreams and goals, more outings, more adventure.
I suspect as well as you work, he doesn't, he wants sex daily you a few times a week that you may also feel used. I am sure that is not his intention but he just doesn't seem to want to do anything other than play games all day and is not interested in working at all.
This is your life and please do not feel guilty if you decide to leave. I call that emotional abuse when someone continues to make you feel guilty if you were ever to contemplate that, he knows that you are and so I believe that he throws that at you.
I think that you are being too nice. Have a proper conversation not one that just suggests you would like him to work but why, what you feel you are missing, that you as a woman (and we do) have changed, matured and need more out of life, that coming home and seeing him playing video games all the time is not a life for him, there could be adventures, travelling, dinners, romance, love and you are missing it all. He truly needs to see that this is now deeply affecting you, your life and your lives together and he needs to do something to play apart of that change.
I hope that he does but if not, I personally would suggest that you remember, it's your life, your man will see his child and he will continue doing what he is doing, nothing but you and your child will be able to move on and find more "life" , "love" and fun he hopefully will remember you as the Mother of his child and a good friend for such a long time over time .
The posters that state you are his Mother, are correct in my opinion.
He is also in my opinion being selfish. You work. You are tired. He is demanding sex daily and then more but not giving into anything you are requesting from him. I believe that is why you are no longer attracted to him sexually, you feel used.
