If you don't want your sibling to take over your lover, then stick to him/her. what sister in her right mind will do such a thing?
At some point, my ex and I have had feelings for each other, shared special moments together and all...of a sudden I'm trying to experience the same thing with my ex's sister?
In the event that it does happen, I know the relationship with my ex's sister won't lead to anything serious.
I think the issue at hand cannot be answered outrightly, coz alot of constraint shld be taken into consideration, first, wht happed between u and the girl/bou b4 u left her or him, this hv to be cleared if ur ex-gurl\boy's brotha is much intelligent and hansome/beautiful and two of u hv a mutual understd, then no then happun.
" This is the status I was greeted with this week on the Facebook page of one of my dear girlfriends.as for me i worship my heart very much..........i can go out with my ex-girlfriend sister if right inside me i discover that we both love and want ourselves........no matter what have cause me to be her sister ex boyfriend.i will establish my love known to her.the amount of love, commitment and investment you had in your relationship with your ex-boyfriend.If the woman is a close friend, the likelihood of this becoming an issue is slim.
