dilemma

If you both don't work for your relationship it will end. That is what most couples forget.. at the start it's interesting, exciting.. at a certain point we do get comfortable with eachother and we go back to our own lives...

Being comfortable with each other that you don't even have to talk is not a warning signal but you have written that he 'spark has gone'.If there is no spark what sort of relationship is that and that too when you are young? Contemplating leaving him in a moment of anger or frustration can happen; but if situation does not improve and there is continuing bitterness with no effort from any side does not bode well for the relationship. If you are comfortable with this person, have some feelings for him do not throw it away.But ensure that chemistry is not lost.

I would say go,we only get one life so we must make the most and be happy,the very fact you are questioning this means you do not feel in love anymore and I am guessing that love is exactly what you want.

It only means that your on the next stage of your life becoming more mature and wanting for more the usual things you did is no longer of interest for it was not of love but the of desire of lust.

yes , love has too many reasons,too many causes and too many meanings.we love our parents,our siblings,our friends,our spouses.but with every person love is of different kind. physics theory says.that when some ones presence increase our breath rate,that one is our love and I am saying its true. love and like are too very close sense words.some time we use to think our liking person as our nonspecializing love is a little difficult task.

It seems like everything is perfect in the beginning. I think you two need to find more to talk about, or do something new together. Keeping the spark alive sometime require doing new things.

Love is a tycoon if you can't handle it, it is a breeze if you love it.
