If you are unhappy then you should communicate to him your feelings and what you want from this relationship, and be very clear and open about it. If he tells you he wants something different then be prepared to walk away. Seriously.
I know lots of friends who stick around waiting for the time when the guy will finally tell them he is ready to settle down, or to have kids. Rarely does the waiting pay off.
TBH most friends of mine who are married and met the guy in their thirties were clear throughout the relationship and demanded more from their partner. I know one women who threw regular tantrums until the guy agreed to marriage. And they got married within 2 years of doing so.
In life nothing is ever easy, and those happy couples, well don't be fooled. Rarely do people meet and the relationship is smooth sailing... You have to fight for what you want and if he does not tolerate it or at best agree to what you want.
Then he is not that into you. And your best option is to move on.
I know one women in her mid-forties now, who spent 10 years waiting for the guy to say he wanted to live with her and have kids. It never happened, and they eventually broke up. Now she is 44 and alone with a smaller pool of options.
My happiest friends are the girlfriends who say it straight and communicate their needs to their partners/lovers.
I am saying all this, because I want to help you...don't be afraid to speak up
