A woman struggling with shame and ridicule

From Full Marriage Equality's comments:

im currently struggling in GSA.. my nephew and i are in the same age. we grew up separately because my brother and his mom were separated.. since we were a kid, i knew i was attracted to him.. im happy when he is around but i dont talked to him much because im afraid he might notice that im attracted to him..

we were in highscool when he had his summer with us.. we were both grown ups, and there goes my feelings again.. i thought i would just ignore him again.. but he seems so interested talking to me.. he even got my number and we talked to each other as much as possible.. it was then when he admitted that he loves me and so i also admitted to him that i feel the same.. but im so afraid that my family might know about us so i stop talking to him which makes him sad and avoided me eventually.

i decided to share it with my sister to seek advice.. but she didnt understands me and worst she told everyone in the family about that.. i was merely moved on.. i had a family of my own and have a child at my young age, but we separated in just few months and raise my child alone. i thought i would never ever fall for anyone again.. until he came back, my nephew..

my heart was filled with happiness when i saw him again.. he stayed for three weeks for vacation and we were un separable, we got every chances we had to show how much we mean to each other.. we were like a couple.. my family warned me so we did it discreetly.. and when he was about to leave he told me that he is living with a girl and it almost breaks me.. all our sweet memories were replaced by sadness.. and he felt bad about that.. but he wants me to go with him and he will leave his girl..

but i cant, i cant leave my one year old son.. and im afraid.. we might lose our family, and there is no turning back if we will do that.. but i cant bear the thought of him sleeping with a girl.. please help me i need advice, how can i make this relationship successful...
