Sorry you are having these problems, parents always want the best for their children, but i as a mother, take a step back, as long as my child is not being abused or treated badly, i feel if they are happy with their partner that is what is important, i don't remember how old you are? but i think everyone has to live their own lives and make their own mistakes.

I am fortunate that i love my son's fiancee and she is everything i ever wanted for him,but even if she weren't i would respect my son's choice in a partner, i think maybe your parents have to do that to.

By all means discuss this with them both and let them know how uncomfortable you feel being stuck in the middle, and clear the air.

I feel you are probably old enough to make your own choices in life and whatever happens your parents will be there to support you.

Maybe you do want more than is being offered, maybe you do want marriage, children etc, nothing wrong with that, as long as Mike shares those feelings and needs , i think you should be just fine, maybe he is not ready for the whole package just yet, but moving in together and being together five years is certainly a committment. good luck.
