Is (Love) really Love

I don't know about most men but it seems they can protect their hearts better than me it seems.How do you say I love you and not mean it is it just a word that is tossed around like nothing or dose it mean what it suppose to.I went through a divorce 4yrs ago after a 20yr marriage my ex said she loved me but left with the neibor now I tried to give it another chance and the first time I have even spoke to a woman in 4yrs I fell in love with her she says she loves me I am her king but tells me all in one day I go from (love) to a riped out heart why? Can anyone tell me why women will tell us this word but realy not no what it means to love or if you women read this maybe you would tell us why?Will someone ever know how to realy love as I do?To give one all your heart even unto death to make a vow and not break it for is not love a vow you make to the one you want to be with forever.How will a person like me that believes in Gods will to send us a partner ever really know if this word is used like it means nothing have we come to this? Where there is no love anymore please let me know maybe you can help mend this heart and the world????????
