There's lots of good advice here, @Settal:
Men will never make you happy. They don't know how. You have to take control of your own life, decide if you want a child alone and stop waiting for a prince. There is life outside of relationships.
Staying in a relationship because you don't feel important unless you have someone is not healthy.
you are expecting way too much in terms of happiness by pegging it on being dependent on another person.
Lots of women go through this. You are not alone. You need to work out how YOU can be happy - and find that in yourself. I find being single extremely freeing and hopeful. It sounds like you’ve got a lot going for you. Stay strong.
Life - living - can be difficult, in many ways. I'm almost twice your age and, believe me, 'the slings and arrows of outrageous fortune' will hit everyone at some point. Everyone will find themselves at some point in their lives where they feel desperately alone. Either because they are truly alone, or because their pivotal relationship is inadequate and leaving them lonelier than if they were really alone.
There is no easy or straightforward solution to what you are facing. You've only known him for 8 months, which may seem early days, but if you are sensing a lack of connection..... it is what it is. If you have any sense of him just being unable to get his head straight (aka as unable to shit or get off the pot...), then have THE conversation. Do it when you are feeling strong and in control, and walk away with your head held high if his response is "sorry, but no".
And when you're at your lowest, remember you are strong, you can pick yourself up, you are still young, you will plough your own furrow, you don't need to take shit from anyone.
