Re: Need good sound advise please.
It's easy to get your hormones tested if you think that's the problem. And if he doesn't understand all you're going through, that isn't a good sign. It's pretty selfish to insist on sex under the circumstances.
Sometimes we want something so badly (a good man who is a good father) that we cling to the slightest hope. You need to be as objective as possible regarding his true contribution to the relationship. Your statement that you do all the "domestic duties expected" of you (plus 2 jobs) is a little overwhelming.
How many jobs does he work? How much child care does he put in? houeshold chores? More importantly, how much support does he give you as a wife and mother and human being? Thinking that shared custody will open his eyes is kind of wishful thinking, especially if he ends up leaving it to his mom, as many do. Selfish people - if he is - don't generally wake up so easily; they just go on finding ways to make things easier for themselves.
The answers to the above questions should give you a fair idea.
Regarding being stifled in your aspirations, having a baby will do that for a long, long time. Perhaps his wonderful family can help out more? If not....sometimes it has to be choice of one or the other. Despite the hype, you can't do it all without significant help.
