I really think people who have had a lot of relationships in the past are douche. I mean they aren't suppose to play with the opposing gender's heart right? If they want to avoid heart-breaks whatsoever they should start being considerable before the idea of a relationship even pops out. Choose the right guy/girl, avoid players, find someone who would never hurt you and etc. I know one guy who broke tons of my female friends hearts. Each and everyone of them had asked me for advice and I told them that he is an asshole but they were all against me thinking that I envied him. Eventually, one by one my friends apologized to me but I am still very disappointed that they couldn't trust me and we don't talk anymore ever since.
