I don't know is any one is second wife or second husband here. But from my experience i want to share something. My mother is been a second wife. First wife of my fathar died leaving a daughter back...that time my mother was married to my fathar for the sake of daugter. Being a second wife she has been never happy.There has been always a invisible wall between my father n mother. I won't say tht they don't love each other. But also thr is no completenes between them.
Foolish heart..love is blind..but don't think by heart...in this type of situation u should think by head. My advice to u will be...wait until all the legal procedure is done...give a break...stay away from ur lover...c wht he does..!! Does he really love you?..N can u face the reality after ur marriage to him..though u said that its ok to u to have him his son..but its not an easy thing!!
