You said you like him.
I believe you.
You said you love him.
I trust you.
But when you told me that you have only known him for months and he is everything to you in life till you would leave behind what you have right now just to be with him, I said: You better think thrice.
A strong lustful affection towards someone is something that we can't control. Feelings will keep on playing around in our head, mentally deciding on either this or that. Sucks at times, but when feelings crosses path with love, mix-emotions are being unleashed.
Have you professed your love to him more than once? Have you tried going out on more than three times of date with him ? Have you really known him very well ? or Have you gotten the "I Heart You Too" signal from him ?
If the answer is no, then I would say it's all just merely infatuation.
It comes and go.
Are you sure ? Then, do allow me to add on another question to determine once and for all.
Have you had sex with him before ?
Oh no ! That's love, but not the kind of love that will turn into a beautiful relationship.
