just don't know if im strong enough to face up to this and end things tho x
You won't be the only person in the world who has left someone they love due to being not on the same romantic page or other such reasons. You're no spring chicken and if you want to be someones wife, if you want to be with a man who values you and wants to be your LIFEpartner as much as you want to be his, have kids then you're with the wrong BOY.
You're in charge of your own destiny so choose how you direct yourself wisely. Don't stagnate yourself because of your fear. In time, you'll be to the stage of indifference to this man and you'll be glad you made the leap of faith in yourself. You're in romantic limbo which suits him fine. What about your wants and needs?
You're 27, certainly not old but certainly old enough to be strong enough not to place your heart in the hands of someone who is too laxidasical, lazy, immature to care for it.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
