The 45-year-old pair have been single all their lives and suffered years of rejection because of their unusual appearance.
But Ganga and Jamuna — who share four arms, three legs and a stomach — say they are now happier than ever after meeting teacher Jasimuddin Ahmad.
“it was love at first sight,” Ganga said.
"When we met Jasimuddin we both felt this was a man who would truly love us. And he does - he loves us straight from the heart,"she added.
"We have been very happy since he came into our lives. We have suffered in the past but we don't want to suffer anymore. We really hope to spend the rest of our lives with him,"Jamuna said.
The sisters, who have separate kidneys and livers, have been single all their lives given their unusual appearance.
Known as the Spider Sisters, the twins were born to an impoverished family in West Bengal, India.
Fearing the twins were a sign of God's fury, their parents deserted them when they reached their teens.
“Now, every night I sit with them. We share a meal on the terrace and talk about our lives. I sit with them in the evening breeze and we share our joys and our sorrows.”
The trio, which lives in a village near Kolkata, India, has been together for seven months but has no plans to get married believing it will not be accepted by the community.
Jamuna said: "We hope he stays with us, it will be a great support."If he wishes it too then we will be lucky. Otherwise our lives will become as anchorless as ever."
