Divine, you are spot on the problems I am thinking about. It's not much his parents or their approval, but as Amandalouise wrote (and she is right) it's really disrespectful to be someones dirty little secret, even it it only for his parents (not other people though), and also my sense of self worth and value is affected. I am sure he does not realize that at all, and few times I tried to tell him, he suggested break up, because he can not give me what I want (he was honest about that from the start) so I shut up.
But what you are most spot on is that he has no retirement plans (zero retirement fund at the time), no travel goals at all, ever or any, he has some projects which I try to be supportive of, but I don't think they are realistic and ever succeed (sorry, he is talented, but his business sense is horrible), no any plans for future. He does not have health insurance, no retirement fund, no car or licence, no money, no prospect, and he does not look too worried about that (I may be wrong about this, maybe he just does not show it). My worst fear is not that he is having someone on the side or hiding something, I know he does not, because we have common friends who have been at his place many times, and yes, he does live alone with his parents, and they are ALWAYS home so he doesn't really have chance with someone on the side. And besides, I know him a long time, he really isn't scumbag, he is good person but meek and non-ambitious, not sure if he has serious depression problems he hides because it's weird not to have any plans for future.
Michelea, some of my friends have been there, it's exactly as he says, even more strange since their apartment is small. There is no chance he could hide anything there. Yes, you are right I am alone, I feel alone, sometimes I feel like I have friend with benefits and that is it. And I am happier when I realize that. Maybe I should think about it that way, but then I should tell him so.
Amandalouise, first of all, I admire your attitude, you sure are completely right. Problem in my case is that I am not so much his dirty little secret, oh, he does gladly show me to all his friends and acquaintances and everyone he meets, he even seems proud, but hides me only to his parents to "protect them and him" because they would "react badly and make his life miserable". So, I am not actually a secret, just for them. He thinks he is protecting them as they are old and sick and would not be able to accept that he will not ever have children, though to be honest, it's his choice.
