falling out of love sin/ god/ church???

I hate when ppl say they "fell out of love" cuz love is forever i mean seriously if you can stop "loving" someone you never truly loved them at all. Maybe you truly thought you did but it is impossible to stop love it is impossible to judge someone you love and thats a huge thing i think if you have to think about whether or not you really love someone the answer is NO because love is so completely obvious i mean if you truly love someone you would know it because you couldnt imagine not having them in your life in one way or another i mean im not just talking the boyfriend girlfriend kind of love im talking friends family lovers... i mean I hate when guys know a girl for a short time and are like ILOVE YOU just so they can get in her pants or make her want them when its not true maybe lust is there and that can most definatly go away and always will but LOVE conquers all... If you love someone its forever not just a year or two or a month like high school i mean kids in highschool fall in and out of  "love" so fast it is really impossible to keep up with your own boyfriends/girlfriends let alone all your friends... Love is a beautiful thing that God gave to us and ppl use it in vane all the time and it really pisses me off cuz the bible says GOD IS LOVE so if we lie about loving someone arent we breaking the comandment that says not to take Gods name in vane i mean if he is love than love is God too they are interchangable cuz you cant have love without god and you cant truly know god without knowing his love. Not only that but CHURCH is represented as the bride in the bible so if we only believe in God or live by our believes when its convenient doesnt that mean we are like cheating on our spouse in a way and wouldnt that be adultery in a way??? And i mean the bible says IF you love me you will keep my commandments so if we say we love God but do our own thing and live by the worlds ways instead of his not only are we breaking the commandments but we are also breaking Gods heart because we are showing we dont really truly love him. And that verse isnt like an ultimatum if you love me you have to keep my commandments but instead its saying if you love God it is impossible not to keep his commandments because you will want to devote your life to him and want him to know you love him and make him happy and proud of you. I am by no means perfect i sin on a daily basis we all do we are all sinners and fall short of the glory of god but if we ask his forgiveness and for his help and guidance he will not hesitate to give it to us. I honestly have no idea where this all came from i just opened the window and started typing so i hope it makes sense and helps someone its mainly me realizing some things for myself Im definately a sinner and I need Gods help to get back in touch with him and i need him to really show me what love is and not human love but the love only he can give the love that fills that emptiness inside that nothing else can fill that love that heals all the pain inside and does so much more than any medicine ever can. I truly want to get my relationship with God back at all costs Im just not sure where to start so im gonna get off here and read a little and talk to the only one with all the answers... JUST REMEMBER GOD IS LOVE AND LOVE IS ETERNAL!!!!!!!
