Please i need your advice.

Please don't insult me, I just want u all 2 advice me.
My ex-boyfriend younger ones like me to the extent that they know am not with there brother anymore, but they do call me every time that if i don't marry there brother, it doesn't stop me from visiting them. 
I don't want to go there but they use to beg me every time to do so and my present boyfriend must not hear this because he is so jealous. Please should i go and visit them or not?
Please don't insult me oooooooo.
