Dating your ex sister
The Frisky: 10 ridiculous celeb excuses for DUI arrests Relationships are not about marking your territory for life.They are about finding someone you click with and can learn from -- and if you are lucky, create a life with.
The Frisky: 20 things that make a man The problem is, Michael has also "friended" my sister, who was an 11-year-old ugly duckling when we dated in high school, but has definitely blossomed since then.
His older brother briefly lived with us during a job transition, and we became pretty good friends.
Shortly after leaving the manwhore, I catch up with the older brother over drinks. They never had a close relationship to begin with, so it didn't cause much trouble, but the man whore started dating a woman recently who has a major issue with the situation.
I'd never date a guy that went out with (and broke up with) my sister because that seems disrespectful to her, but that's just me... so it depends if you're prepared for that risk from my perspective, I'd say it's an unfair thing for you to do to get between the sisters, BUT it depends how strongly you feel.
Most sisters will ultimately put each other before a boy, and if you think it's too soon for your ex, then the sister may end up being forced to dump you through family allegiance etc...
